I want to retag all my music collection (MP3, OGG, etc) with replaygain info, but I don't want them to lose their original file timestamp as sometimes I want to know when I added a file to my collection as it helps me find them by sorting them in my favorite file manager by date.
So here is my question: Is there a tool (or a commmand that I can use in a batch file) that I can use to batch-backup only the timestamps of all the files, before I do the retagging and then to be able later to restore their file timestamps back? If it can be done recursively to all folders beneath, it will be extra nice!
