[name]TDS will only work with the file names that have TDS in them.
You could enter TDS into the J River search to isoloate everything with TDS, then do "Fill Properties From Filename" for [name]TDS.
If there are file names that don't have TDS but have some other common characters you can change the J river search parameters and the "Fill Properties From Filename" parameters accordingly.
If there are no common characters, but just a cornucopia of random numbers and letters, then this method wont work without some manual changes done to the file name.
Some people use "PvdImport" to add tags to their videos. Once the videos have tags, J River can rename the file and directories based on the tag information.
I have never used PvdImport so i cant say how well it works.
I found manually renaming then using "Fill Properties From Filename" so simple and quick that i haven't bothered to try any other way.
A few months ago i spent a couple hours a day for about a week to tag over 1400 videos. Now that its done i spend maybe 5 minutes a week tagging new videos as i acquire them.
If all you are trying to do is clean up your file names, im sure that it would take less time to manually change them than it would take to find some magical fix.
If you want to add detailed tags look into PvdImport or look here
