Applying default UNIX permissions
When Apply default UNIX permissions is checked, default UNIX permissions
set in the Linux client are applied instead of Windows ACL permissions
when uploading or creating files and folders. Applied permissions are
the same as permissions applied by the UNIX command umask. The default
umask value is 022.
Noteļ¼
For Windows ACL enabled shared folders (all shares excluding "photo" and
shares on external drives), please run the chmod command on your Linux
or FTP client to change folder and file permission types from Windows
ACL to UNIX.
Enabling this option might cause inconsistent permission issues between different protocols. To avoid inconsistencies, we suggest leaving this
option disabled.
