Files are deleting themselves?? Why??

I have the same problem and I believe because the syncing takes way too long to do that any other device that access the dropbox will take the active devices setting of files and set dropbox website to replicate what the active device has currently. I have also had many file that were removed now are coming back. I have not accessed dropbox from any other device except for my main computer and files are deleted (like over 1,000 files) and other files added that were not requested. From all of the posting on this forum stating the same issue and the only solution that is provided is that the problem is on our end then I am not sure if Dropbox is a solution for me anymore. It is a shame since I have been a supporter of Dropbox for many, many years and referred many people to Dropbox.

I have the same problem with files deleting themselves, only just started I've have never had a problem before. Not Good, i'm the same a supporter but I cannot keep restoring files.

All files were deleted on the 4th of this month must be a fix?

It's important to note that files don't delete themselves, it's always the direct result of input from a user or connected device.

I had this problem - a file seemed to be deleting itself.  I had two files in the same folder whose names differed only by case (not good practice I know): makeRules.hs and MakeRules.hs.  Whenever I restored MakeRules,hs, dropbox would immediaely rename it to makeRules (Case Conflict).hs

Solution: don't have files whose names differ only by case.  If you need this for some reason, exclude that folder from dropbox synchronisation.

The same things happens to me and I agree with the other users I have not done anything.  I will have a folder I called ICPMS and within the folder have a subfolder called Python.  One day the folder is there the next day it is gone and I have to restore it.  then a week later it might be gone again.  I have dropbox on multiple computers all logged in with me.  Sometimes since we work at a college we have to install and un-install dropbox on a computer but that shouldn't do it as we don't lose the other files.  We are starting to lose really important files and we are thinking of stopping using dropbox for any important files.  I just bought another drive to make continuous backups for this problem.   I agree with the other users that somehow dropbox mysteriously deletes folders and files for no reason and there is a bug somewhere.  I have not found a pattern yet.   

has anyone been contacted about this? I am missing files and I remember this happening. Did dropbox restore the files? Dropbox tech guy can you chime in on this?

Hey guys...over 4000 files deleted by themselves....including active files that my client need...what is going on???

over 4000 files deleted by themselves....what is going on???

Dropbox is not capable of deleting files on its own. Either you, another process on your computer or another device connected to your account had to initiate the deletion. Use the Events page and Previous Versions information to determine where the deletion occurred.

Regardless of you thinking dropbox cannot delete the files, it is and as you can see its happened to a number of people and they all cannot be wrong. If Dropbox is ignoring the fact that something is wrong I suggest those effected move to another supplier. I had it happen to me once touch wood it has not happened again. As explained to a dropbox rep the files deleted were word, excel and PDF files all jpeg files were not effected. On your comments today who or why would you go through and delete 4000 files. I also have a google drive account with approximately the same amount of files on it and have not had a problem.
