What are "Recover" files?

I understand what you are trying to say, I just let you know what greyed-out files mean.
If the greyed-out file was in Recovery section, you can simply remove it from the Recent as of now as it is restored.

Hi all,
OnlyOffice app has been on Mac (M1) for 3 weeks. A very bad thing happened to me today. While my Word document was open, I deleted the folder where the document was located. I also emptied the recycle folder. But OnlyOffice neither warned me when deleting the file, nor did the operating system prevent me from deleting the file. I see the file name in the “Recent Files” tab, but since the file is not in the relevant folder, it appears with a gray background and OnlyOffice cannot open the file. The strange thing is that while I was working on the file with OnlyOffice, I continued working on OnlyOffice for hours with the file I deleted from the operating system. Now, if OnlyOffice allows me to work even though this file is not on disk, is it possible that it has kept this file temporarily in a folder? Can I get this file back? The file is very important to me.
Thanks in advance for your help.
