Problem
How can I control the file mode? Can I set or reset the 'system', 'archive', or 'hidden' attribute of MS Windows file (and directory) by using UNIX commands?
Answer

Solution: Unfortunately, the FAT file system does not support permissions similar to UNIX permissions (i.e., 'Read/Write/Execute' for 'user/group/world'). While writing files from UNIX to MS Windows, NFS-Server applies the following rules:

UNIX attributes DOS attributes
-r--r--r-- FILE_ATTRIBUTE_NORMAL
-rw-rw-rw- FILE_ATTRIBUTE_SYSTEM
At least one execution allowed FILE_ATTRIBUTE_HIDDEN
At least one write not allowed FILE_ATTRIBUTE_READONLY
for all files FILE_ATTRIBUTE_ARCHIVE

You can set/reset attributes by using UNIX commands. And so you can set up attributes of MS Windows file (for example, the command 'chmod +x <file name>' will produce the 'hidden' <file> on the MS Windows box).
