I just installed SeaDrive 0.85 on Windows 10 Pro, and it is showing a drive with 90.9TB capacity. Of course, it's not 90TB on the real server. Can you check and fix the bug please?
It always show 90 TiB. If it is improved it would be the best to use the quota settings.
I installed SeaDrive in different versions, also 0.8.5, on several Windows 10 systems. After the first installation and restart of the pc, the quota settings of seafile are also shown correctly in windows explorer.
