Attached documents are not visible by issues

[ToTgg]

I would like to ask about associating uploaded files in an issue with DMSF. When opening the DMSF file explorer, the .issue directory is visible initially. However, after some time, both the issue and the .issue directory in DMSF become inaccessible.

It seems to disappear every month, and I apologize for not being able to find any reason for it.

I think that .Issues system folder is never deleted. I think that you will have to investigate when that happens. Otherwise we won't move further.
