Learn how to secure the Dropbox app on your phone or tablet by setting a passcode or Touch ID fingerprint scan. This 3-minute video applies to recent versions of the Dropbox app on iOS devices such as the iPhone and iPad. The narrator of the iPhone tutorial is Ian Lamont, author of Dropbox In 30 Minutes.
I recently made a huge mistake in Dropbox. From my desktop computer, I deleted two folders — one shared, and one not — that collectively contained more than 9,000 files, including mission-critical files for my business. I watched in horror as Dropbox synced the deletion to my master Dropbox account, which then replicated to all other devices linked to the same Dropbox account.
Now, if you have read my book Dropbox In 30 Minutes or have seen some of my other videos, you know there is a relatively easy way to restore deleted Dropbox files using the Dropbox.com website. You can see the video here.
But, when you’ve deleted thousands of files and hundreds of folders, it’s a huge hassle to manually restore all of them. It can take hours to hunt around on Dropbox.com, find the trashed folders and files, and right-click to restore them.
Fortunately, Dropbox offers a way to get back all of the files and folders at once. It involves the “Events” tab on the Dropbox.com website, which is a list of all Dropbox activities (updates, deletions, etc.) going back one month. The video below describes how to do it. This is the method I used to get my 9,000+ files and folders back to the way they had been before.
Note that this method will not work if the deletion event took place more than one month ago. In addition, if you have added files and folders to your Dropbox account since the deletion event, it may cause issues when you try to restore using the Events link.
Without further ado, here’s the video:
What’s the best way to import folders to Dropbox? A reader was wondering which of the following two setups worked best:
When I transfer a folder from my hard drive to the dropbox website, the hard drive copy of the folder stays there so the file is on both dropbox and the hard drive.
When I transfer a folder from the hard drive to the dropbox folder the hard drive copy of the folder is deleted and is just listed on dropbox so there is no file on the hard drive but just listed in the dropbox folder.
Which is correct? Should I have folders in both the hard drive and dropbox or dropbox only?
As I mentioned in my Dropbox book, It’s important to remember that the core feature of Dropbox is the ability to automatically synchronize anything that gets “dropped” into it, wherever it may be installed — the Dropbox folder on your desktop or laptop, the Dropbox app on your iPhone or Android phone, or Dropbox.com. It looks like this conceptually:
For this reader, the ideal approach would be to install Dropbox on your computer and then move the folder from your hard drive to your Dropbox folder on your hard drive (which will then sync with your Dropbox folder online and on any other computer using the same Dropbox account). Note that this does not delete the folder from your hard drive — it simply moves it from one location on your hard drive (for instance C:/My Documents/Janice) to another location on your hard drive (C:/Desktop/Dropbox/Janice). Whenever you update the file stored in your Dropbox folder on your computer, it will automatically sync to the other locations you have Dropbox installed as well as on Dropbox.com.
I do not recommend uploading the folder to Dropbox.com and deleting the folder on your hard drive (that is, without installing the Dropbox application on your computer). The reason: If something happens to your account (for instance, you can’t recover the password or Dropbox has a massive outage) you would lose the data or be unable to access it in that folder.
Another bad option: Copying the folder to Dropbox. This leads to two separate versions of each file in the folder (potentially thousands in all), and the potential for the unsynced versions of the files to be opened and edited.
What are Dropbox comments? In brief, Dropbox comments enable users to append comments and reference other collaborators from individual documents stored in Dropbox. This post will outline how Dropbox comments work, and serve as a review of the feature.
The idea of adding comments to a document is not new. Anyone who regularly shares Microsoft Office or MS Word documents with other people should be familiar with the commenting feature, which lets users attach comments to cells, phrases, and other elements within the documents. Google Docs also has a slick commenting feature.
Dropbox comments are a bit different. Rather than appearing inside of the document or file itself, they are appended to the Web preview of the document. In addition, Dropbox comments are not attached to specific elements within a document. That is, if I highlight a word in the preview and then type in the comments bar, the comment won’t be attached to that word as it would be in a Word doc. Dropbox comments can’t be edited, either, although it’s possible to do other things with them (see list, below).
There are two ways to add a comment: From the Finder/Folder on your desktop, or via the Dropbox.com website. Here’s the view from Finder. Look for the “add comment” option when right-clicking on the selected file:
Once making the selection, you’ll be brought to the Web preview on Dropbox.com (login required). You can also add a comment directly from Dropbox.com. Here’s the interface, with a preview of a Microsoft Word document (the manuscript for our Virtual Office book) on the left and a note to myself on the right:
Clicking Post will add the comment. If it is a shared document, other people will see the comment, kind of like a shared Google Docs file.
Other features of Dropbox comments
Here is a short list of additional features:
- The ability to “@mention” collaborators in a comment by adding an “@” symbol along with the person’s name. The person must be a collaborator in a shared Dropbox folder. He or she will be notified of the comment being added.
- The ability to “like” comments by clicking a star underneath the comment.
- The ability to resolve comments when an issue has been addressed or closed.
- Comments can be deleted, but not edited.
The Dropbox comments feature is useful, especially considering they can be appended to files that normally can’t be commented on, such as image files. However, once the files leave Dropbox (for instance, via export or unsharing) the comments are not ported out. In addition, the comments feature does not appear in the Dropbox mobile app (I tried iOS 8.3), although I would expect Dropbox to at least add a comments previewing feature in the future.
Have you tried Dropbox comments? What do you think?
Dropbox, like many large technology companies that store or host content uploaded by users, has to follow the Digital Millennium Copyright Act (DMCA). The DMCA helps copyright owners (such as musicians, film studios, authors, and others) prevent users from sharing copies of songs, movies, books, and other copyrighted data for free on the Internet. Practically speaking, if you try to share an mp3 or other music file, you will likely run into problems.
The way that Dropbox follows the DMCA is to prevent its users from sharing links to materials that it determines are copyrighted. So, if you share a link to a Dropbox folder that contains a copy of an old Jackson 5 mp3, any user who clicks on that link may see a message that says something like, “Certain files in this folder can’t be shared due to a takedown request in accordance with the DMCA.” When Ars Technica reported on a 2014 incident involving a copyrighted video file, Dropbox offered this clarification:
Dropbox did confirm to Ars that it checks publicly shared file links against hashes of other files that have been previously subject to successful DMCA requests. “We sometimes receive DMCA notices to remove links on copyright grounds,” the company said in a statement provided to Ars. “When we receive these, we process them according to the law and disable the identified link. We have an automated system that then prevents other users from sharing the identical material using another Dropbox link. This is done by comparing file hashes.”
Dropbox added that this comparison happens when a public link to your file is created and that “we don’t look at the files in your private folders and are committed to keeping your stuff safe.” The company wouldn’t comment publicly on whether the same content-matching algorithm was run on files shared directly with other Dropbox users via the service’s account-to-account sharing functions, but the wording of the statement suggests that this system only applies to publicly shared links.
However, I have not seen cases of Dropbox unilaterally removing copies of copyrighted files from Dropbox accounts. Why not? Because if I place an mp3 file of Jackson 5’s “ABC” in my Dropbox account, Dropbox has no way of knowing whether the song is pirated. If I legitimately purchased the song or made a copy for my own disco-themed workout session in my living room, Dropbox does not have the right to remove it. The company can certainly prevent me from sharing it for free (per the DMCA) but for the time being Dropbox will make no additional assumptions about the legality of such content placed in a Dropbox folder.
Dropbox’s official DMCA policy is listed here.
A reader of Dropbox In 30 Minutes, 2nd Edition, recently contacted me about a situation involving a shared folder filled with photos. His question: If he is not the owner of the folder, and the owner decides to delete or unshare the folder, will he be able to keep copies of the photos? The following post explains how to keep shared files in Dropbox if you are not the owner of the shared folder in question.
Before I dive into the details, a key concept to understand is who owns the shared folder. Let’s say you belong to a shared folder with a friend. If your friend is the owner of the folder, then you will have secondary permissions. What does this mean? At the very least, you will be able to view the files, or maybe edit them, and upload new files to the folder. But you won’t be able to delete them. You may also be able to invite new people to the folder, as long as the owner has granted you permission to do so (not everyone does this). Later, the owner may also decide to transfer ownership to you, at which point you would gain the power to delete files, invite new people, or make other changes.
If the owner deletes the folder, then you will also lose the files in it. However, if she unshares it she will be given the option to allow you to keep a copy (she will be prompted with a checkbox that says “I want my collaborators to keep a copy of these files.”) This second option is preferable. However, if you are not sure how your friend will handle this later on, my advice is to download the files now so you have a copy. You can then bring it back into Dropbox.
To do this, follow these steps:
- Log onto Dropbox.com and go to the folder in question
- Select all of the files in it (click the top file once so it is highlighted, then use the keyboard shortcut Ctrl-A on a Windows PC or Command-A on a Mac, or go to Edit>Select All in the browser menu).
- Click the download link that appears at the top of the screen (see image below).
The photos will be downloaded to your hard drive as a zipped archive (.zip) which you can then transfer to Dropbox on your hard drive or unpack it and move the files to a new Dropbox folder that you control.
One of the most-asked questions about Dropbox relates to deleting files. Many users assume you can simply delete or trash the file from your desktop. It won’t work! In this blog post, I’ll explain how to permanently delete a Dropbox file. If it’s still not clear, a video at the bottom of the post shows exactly what to do.
As I explain in my Dropbox guide, deleting a Dropbox file is kind of like killing a vampire. Just when you think you’ve trashed the file, it pops up alive and kicking in another location! That’s because Dropbox stores multiple copies of the same file, and the only way to kill it for good is to wipe it out from the Dropbox.com website. Several steps are involved, so please be patient while I explain the steps involved:
- Go to Dropbox.com, and log in
- Find the file that you wnat to delete
- Right click over the file’s name
- Select Delete. You will be prompted to confirm the deletion.
- VAMPIRE WARNING: The file is not dead yet!
- Click on the trash can icon at the top of the screen (it says “Show delete files” if you hover over it)
- The file you just deleted will reappear in the list, but it will be greyed out
- Right-click on it again, and select Permanently Delete.
- You will be asked to confirm if you want to permanently delete it. This is your last chance to change your mind, so if you are sure, go ahead and confirm!
- VAMPIRE ALERT: If you want to bring it back to life, right-click and select Restore.
That’s it! This method also works for people who want to delete Dropbox folders.
The video version of this post is included below:
A Canadian reader recently contacted me about a problem. He had subscribed to Dropbox Pro and now had access to 1 terabyte of available storage space. Unfortunately, his hard disks on his Windows PC did not have enough space to sync the entire Dropbox account. How could he set up Dropbox so his hard disk wouldn’t be overwhelmed by photos and other files?
Fortunately, there is a solution. In this post, I’ll explain how to use Dropbox’s Selective Sync feature to limit which folders on your hard drive are synced.
Selective Sync is activated from Dropbox preferences. Follow these steps:
- Open Dropbox settings on your Windows 7 or Windows 8 computer (click the Dropbox icon in your system tray, and then the settings icon)
- Click Preferences
- Click Account
- Click the “Change Settings” button next to “Selective Sync” (see screenshot, below).
- Use the checkboxes to select the folders you want to sync to your PC. The others won’t be synced.
Here’s what the setting looks like:

How secure is Dropbox? This can be an uncomfortable question for Dropbox users who save sensitive files or other valuable data in their accounts. Think of business plans, legal documents, financial projections and, er, personal photos that you wouldn’t want to fall into unfriendly hands. This data is stored in “the cloud” — remote Internet servers that neither you nor Dropbox fully controls.
While Dropbox goes through great lengths to reassure users that it takes security seriously (it points to technologies such as Secure Sockets Layer and heavy-duty encryption, and claims employees are prohibited from viewing the content of users’ files) there have been security incidents, including a bug that allowed any Dropbox account to briefly be accessible without passwords a few years ago. The company quickly fixed the problem and claims additional safeguards were put in place. The company now offers the option of using two-factor identification. Nevertheless, there is no guarantee that some other bug, error, or hack might expose Dropbox user data in the future.
In addition, Dropbox users themselves may be the source of problems. If you are sharing a folder with 100 users, a couple of them are bound to be using easily guessed passwords to guard their accounts (the names of pets or first-born children, “password”, etc.). Sharing links can also lead to problems, if the wrong link is shared or someone posts the link online or in some other public forum.
Despite these issues, millions of people use Dropbox every day. They’re aware that there’s a risk, but are basically making a tradeoff. They are putting more value on the convenience of accessing and sharing files over the Internet for free (or for a low cost), and discounting the chances that the data may be lost, stolen, or exposed.
As I said earlier, it’s an uncomfortable feeling for some people. If it’s too much for you, don’t use Dropbox — or only use it for non-sensitive data. Also be sure to set a passcode lock on the Dropbox mobile app, be careful of who you share links with, and regularly delete old Dropbox links by following these steps.
In addition, be very cognizant of local laws and workplace regulations governing storage of files. I recently received an email from a reader who asked about sharing sensitive workplace files. He claimed he worked for a local state agency. In my response, I said:
“If this is truly sensitive or valuable data, I urge you to think carefully about putting it on Dropbox. As I pointed out in the book, there have been security breaches affecting Dropbox in the past, and when it comes to sharing confidential state financial information, there may be rules or laws that govern how it can shared/transmitted electronically. Making a call to the state CIO or senior IT manager to see how they recommend handing this situation would be an advisable move.”
Even if your company allows Dropbox in the workplace, it may forbid ex-employees from keeping old files. If you leave the job, be sure to go into Dropbox and leave shared folders and delete copies of files as required.
How do you delete Dropbox links? There are lots of situations in which you might want to get rid of a link and make sure no one is able to use it ever again. Maybe the link is to a file in Dropbox that is sensitive and you are worried about it being shared with strangers. Or perhaps the file is outdated and you don’t want people to see it anymore. Whatever the reason, this post explains how to delete Dropbox links.
The post was prompted by a message I received from a Dropbox user who was worried about an old video she had created and stored on Dropbox. She wrote:
“What if I sent an email and attached a dropbox video, but, it turned-out the incorrect version and I needed to “delete” it so no versions of it can be replayed. Is there a way to make that video “Unplayable”? I learned that we can delete “shared” folders and remove shared users … but what about a dropbox video that was “attached” to an email. The next time the email is opened, I need the video link to be broken. Is there a way to do this?”
It’s actually very easy to delete Dropbox links. Here’s what I told her to do:
- Go to Dropbox.com and log in
- On the left side of the window click “Links”. You’ll see a list of all of the links you’ve created.
- On the right side of each link is an “X”. Click the X to delete that link. You’ll be prompted to confirm each deletion.
- Once the link is gone, no one can use that link, but you will still have the file in Dropbox (and can create a new link for it later, if you want)
On Dropbox.com, here is what the Links screen looks like. I am hovering my mouse over the “X” that let’s me delete the link in question:
