The icon of my pCloud virtual drive P:\ has a red badge with an exclamation mark when shown in Directory Opus. Since this badge is not in Windows Explorer, I think it might be a problem of Directory Opus.
Directory Opus
Windows Explorer
If you close the window and open a new one, is the exclamation mark still there?
Is it on any folders below that drive in Opus or File Explorer?
(It's also possible File Explorer just isn't showing overlays, or has hit the small icon overlay limit in a different order to Opus and cannot display that particular overlay even though it's there in both programs. The overlay itself comes from either the OS or a shell extension, and Opus just displays what it's told to, assuming it isn't a status icon overlay via either Opus labels or something like SVN.)
No, the red badge is always in Directory Opus, even if I restart Directory Opus or if I restart my computer.
I have also two Google Drive and one Icedrive virtual drives and they don’t have a red badge in Directory Opus.
