There are various reasons why files can go missing. Use this troubleshooting guide to figure out what happened and, if at all possible, get your files back.
If the files were in a shared folder, and the folder seems to be gone or incomplete, check if you're still a member of that folder. You may have left the shared folder, you may have been removed from the shared folder, or the owner unshared the entire folder from the group.
Check if you need to rejoin the shared folder.
Check if the folder is still shared.
If the folder is no longer listed among your current or past shared folders, then it was either unshared, or you were removed from the folder. You'll need to contact the owner of the folder to find the reason. Only the owner can remove a user from the folder or unshare the folder. If the folder is still shared, then other members can usually invite you back to the folder.
Files you've uploaded to your account, including recently deleted files, can be found on the website. Sign in to dropbox.com and type the name of a missing file into the search box. Use the Advanced search link (which will appear after you type something in the search box) to search for deleted files. Alternatively, you can just press the trash can icon next to the search box to show deleted files, which will appear in gray. Learn more on how to search for files.
Your search may show that the files were actually moved and not deleted. When you move files, Dropbox treats this event as you deleting them in one place and adding them to another place. If you move (or just rename) a large number of files, then you may receive a notification that some files were “deleted” and then miss the notification that they were “added” later.
Dropbox saves all deleted files for 30 days (and longer if you pay for the Packrat option). You can restore these files from the website. Follow the instructions to view and restore any deleted files that can still be restored.
Please note that it's possible to restore multiple files at once. Use these shortcuts to select multiple files or folders and then restore them all with a single click.
We'll be happy to help you restore the files. Please go to your Events page and let us know which events you'd like to undo by sending us links to them. See instructions for getting the correct links.
Check the file's history.
You can see which user and computer deleted a file by looking at that file's previous version history on the web. If the files were in a shared folder, you'll see which member removed the file. You can restore files from this view as well.
Check the Events page.
You can also see who made a change by looking at the Events page on the website. This page will also show you when you left (or were removed from) a shared folder.
It's important to note that Dropbox will never remove your files on its own (say, because you're over your storage limit). The Dropbox application only responds to changes after they happen. If a file isn't where you expect it to be, then the reason is due to an event on a linked computer, mobile device, or the website. Using the previous instructions, you should be able to identify which account and computer removed a file.
Even if you go over your storage limit, nothing is deleted. Syncing just stops and will resume if you bring your account under the limit.
The short answer is, “Mistakes happen.” Whether it was an accidental click of the mouse, a move instead of a copy, or just an unfamiliarity with how Dropbox works, the most common reason is that people accidentally remove files from their own Dropbox folder.
That said, here are other causes of deleted or missing files:
Hard disk problems, including bad disks, or disks that are not ready when the Dropbox program runs. If Dropbox doesn't see known files when it starts, it will assume you removed them while Dropbox wasn't running.
Antivirus software that quarantines files. These programs can remove or block access to files.
Disk scanning software (for example, backup software) that locks out Dropbox and makes it appear as if files are missing.
Programs that modify files in your Home folder, which usually includes the Dropbox folder. Some audio and image management software programs do this.
Multiple linked computers with the same name. Perhaps you gave your PC to your mom, and she deleted some files. If this PC has the same name as your new computer, you might not realize a second PC is in the picture. (Yes, this has happened.) If the computer is linked to your account, then you can see the last used IP address for it on your Security page.
The Dropbox folder is just a normal folder on your hard drive, so any changes to it are synced to the website. Internet connection issues may delay the actual syncing to a time when “no one was at the computer,” but the timestamps do represent the actual time that Dropbox synced the event.
If you can't find a file, then one of the following is true:
The file was deleted more than 30 days ago, and you don't have Packrat.
The file was in a shared folder that's no longer shared or joined (see above).
The file was never actually uploaded to your Dropbox account. You uploaded the file to a different account, didn't give Dropbox enough time to upload the file before deleting it, or never placed the file in the Dropbox folder.
If you suspect any of these situations, then please send us a request with the exact name of the missing file. We can search the logs for you to see if the file ever existed in your account.
