Here I suggested “net use” was not necessary, which also avoids the plain text credential issue. Can any try? Reporting back to the link above (positive or negative) might be useful. The topic here began on local drives. Perhaps @pribis could clarify what that meant. What variety of local drive, and how and when was it added?
I also commented on possible inability to browse network paths. See the remarks on “Network Neighborhood”. My systems are all too new to do “Network Neighborhood”, so any Duplicati test will require an older Windows.
I also pointed to Microsoft documentation supporting what we’ve said here – letters are not globally assigned. Despite the Microsoft warnings, the new letter from my USB drive showed up everywhere - including Duplicati.
I’m trying to summarize here too because maybe this thread has wandered, but only @pribis knows for sure.
