Is your feature request related to a problem? Please describe.
often there are sync issues when desktop client removes or changes lot of files by mistake e.g.

desktop client #4016
desktop client #4035
desktop client #3444

As the sync is pretty fast and the error might be not obvious, this results in hundreds or thousands of deleted files or files existing as different versions.

Describe the solution you'd like
Please add a possibility to manage this files from command line e.g. occ or other tool which allows user to perform mass recovery of files (and remove invalid file versions) after such issue.

Good starting point would be the server activity history where the user could review changed files and "undo" the action like restore previous version and delete new one or restore deleted files..

Describe alternatives you've considered
If the problem affects multiple files in different folders the only alternative seems to be a server restore. as manual versions handling is impossible for more than couple of files..

Start by reviewing the occ command surface and the server activity history referenced in the issue, then trace how trashbin and file versions are currently handled. Done would require a defined per-user command workflow for reviewing changes and performing mass recovery or version cleanup, with its scope and verification criteria agreed first.
