Feature Request - File modification detection scheme
Be able to specify whether acrosync uses
file size + modification date
to detect whether a file has changed. The equivalent to rsync's --checksum option.
This is not hard to implement, but I wonder if there are many users who want this feature. Most programs do not mess around with the modified timestamp when they update a file.
