Boxcryptor looks pretty good. Thanks!
But I have a question regarding security. It looks like that boxcryptor mounts a FAT32 drive, but it is not possible to set any permissions on a FAT32 drive, right?
Why doesn't Boxcryptor mount the drive as NTFS?
Yes (or no?), permissions can't be set on the BoxCryptor drive yet. There are several reasons why a BoxCryptor drive is mounted as FAT32, e.g. because Windows Search only works on the BoxCryptor drive when it is FAT32.
We might consider changing this in the future - until then you could set the permissions directly on the underlying encrypted files.
