1. Tried to open file I know I kept in one of synchronised folders, but did not find it.
2. Checked online in Dropbox, no luck, file disappeared as well.
3. Checked deleted files - no luck, missing.
4. Checked event log - yes, marked as added 2021-10-18 23:18 so should be covered by 30 days history
5. Size shows correctly, but when truying to download I get file with 0 size.
6. The same for previous versions of the same file - same story, file added, empty when attempting to download, all missing from both drive and "Deleted" folder.
Any idea how I should proceed? Obviously files were added to the drive (according to event log), less than 30 days ago, cannot recover them. Also I do not recall deleteing anything permamently from either hard drive nor cloud.
