'Recover files' + grayed-out filenames

Desktop editors
1

I can’t recall what the ‘Recover files’ label refers to.
It appears as a separate listing from ‘Recent files’ without any explanation.
The implication is that a file wasn’t saved ‘normally’ but has been ‘recovered’.
In what situations does this happen?

Also, what do grayed-out filenames mean?

Thanks

(I may have asked about one or both of these before but haven’t been able to find the information currently,)

Hello @mk7z,
Recover files refers to files that can be restored after Editors unexpected crash, etc. - How to recover unsaved documents in ONLYOFFICE Desktop Editors
The grayed-out names are the files which are no longer accessible for the recovery
