Hello @CU, sorry to hear that you are missing files in your Dropbox account.
The events page logs all the actions taken in your account, up to your version history.
If you cannot see the deletion events there, most likely the files were deleted outside of the version history.
If the deleted files were part of a shared folder, you can check here to see if you have the folder added back to Dropbox.
Let me know if I can assist you further.
