Question or Issue
Deep plumbing alert!
I use a Fujitsu ScanSnap ix500 scanner with my MacBook Pro. It appears I may have made the mistake of changing a folder name via Finder when that folder happened to be the ScanSnap Home (SSH) folder, which is the destination folder for scanned documents. That folder is also within Dropbox. For example, the original SSH folder was [Users/me/Dropbox/My Inbox] and the [My Inbox] folder name was changed in Finder to [My Scans]. The name change was done recently, and with plenty of my recovery period remaining.

There is no longer any record of files in the now-renamed [My Scans] folder in Dropbox (online or on my device) before the date of the folder name change. There is nothing in the deleted files folder (online or on my device), including a reference to the folder name change, so I am not able to view/restore as I normally would with deleted files. However, the files (or at least thumbnails of) can still be seen in the ScanSnap app but they cannot be accessed, as an error message comes up showing the doc with the old [My Inbox] path is not accessible.

Maybe the question is, how can files (20k+ files) get removed from Dropbox without any trace or record of those files ever being there? Any help or insight would be appreciated.
