Copy/Paste Issue on mounted volume

[NYSGFC25]

Hi,

This is my first post, so bear with me if I am not describing the issue properly or confusing with terminologies. I ran into an issue which looks like a bug to me. If anyone knows how to fix, I would appreciate it.

I use Box Drive (online storage solution) at work. The main folder for the Box Drive is created as a JUNCTION and a volume mounted. Not sure how to upload the screenshot, but below is what I get at CMD.

> dir
07/14/2025 08:28 AM <JUNCTION> Box [\??\Volume{ABCDXYD}\]

Box is the name of folder where the drive is mounted and ABCDXYD is what looks like GUID

When I copy a file using “Explorer” and then paste it using FC, nothing happens. However, if I drag the file from Explorer and then drop it in FC window, it works as expected. If both copy and paste actions happens within FC, there is no issue. It’s only when source is Explorer and Destination is Box Drive folder in FC.

I have had similar issue earlier too, where, if I copy something in Explorer, close it and then try to past in FC, nothing would happen (no copy/paste). I have been ignoring it thinking it's some kind of limitation. However, in the above scenario, the copy/paste fails even if the Explorer is still open.

Has anyone run into this issue?

FC Version: FreeCommander XE 2025 Build 921 32-bit public
OS: Windows 10 22H2

PS: I have screen-recording but, as mentioned above for screenshot, I am not sure how to attach it here.

Thanks,

Do you run FC as admin ?
If yes, Windows will prevent action from the normal running Explorer
into the FC process with higher rights.
