I recently moved my music collection from a local hard drive on Windows XP to a networked attached storage device. The device is a ReadyNAS 600, the OS of which is based on some variant of Linux.
In Mp3tag I have 'Preserve file modification time when saving tags' unchecked. When operating on files on a local drive the modification times are updated correctly, but they're not being updated at all on the NAS.
Any ideas of why this would be? When I use another program, say Notepad to edit a text file, then the file modification is updated on the NAS.
When the above option is disabled does Mp3tag do anything explicit to change the modification time, or is up to the operating system? How does Mp3tag preserve the modification time when this option is enabled?
