I seem to be able to add a network adress or FTP server directly in Windows explorer. It can't handle SFTP though. I know about Filezille, but there I can just access the server, not mount it. I need to mount it because I want to be able to access those files from programes on my computer, and not have to copy them around all the time.
I would want it to be open source. It does not need to mount the drive, just being able to access it with windows explorer as a folder like Google Drive is enough for me.
I'm not looking for a VSCodeplugin, as that was recommended to me. The reason is that I'm not using VSCode, so it wouldn't help me in any way.
