hello! I'm really sorry, if I'm repeating a thread, but I couldn't find any similar. So, I'm totally new to Linux and I also have Widnows XP installed on my computer. And my problem is, that when I log in as root I can't change permissions to allow my other user to view and modify files from windows. One of the folders (Documents and Settings) is problematic and I don't know how else to change permisson so I could use the files that I created in windows and my other user.

FAT16 and FAT32 uses attributes like archive, hidden, system, and read-only which Linux does not work with. When you mount these filesystems, you have to specify the umask that will be global throughout the mounted device. You can increase security by specify gid. This will make sure only certain groups can access the FAT partitions. After you mount the FAT partitions you can not change the permissions. Also this goes the same for NTFS but writing to it is experimental. For NTFS partitions, I suggest mounting it as read-only.

In both Linux and DOS/Windows, it is wrong to say folder. The right word is directory.

BTW, there is several questions about this.
