A folder or external USB drive can be mounted for remote access from the Windows File Explorer. WinFsp will need to be downloaded and installed (https://winfsp.dev/rel/). Then to mount, simply right-click → Remote Mount.
Note: Only one folder or external USB drive can be mounted.
The mounted folder or USB will appear as "Local Disk (E:)" in the Windows File Explorer.
To unmount the drive, go to Remote Mount in Amber iX Desktop and Unmount.
