The filename is currently track number followed by title. I would like to change it to Disc Number, track number and title. When I use the Convert %discnumber%%track%%title% on the first track 01, the preview shows the 01 tracks as 11. How can I fix this?
I have it worked out. The problem was when I did Convert, Tag Filename the file name contained the 01 with the file name, so when I did the change it included the extra zero.
If you use COnvert>Tag-Filename then a completely new filename is created and nothing left from the old filename.
So your description does not really look like the solution to your problem.
If you need further assistance, then please show a screendump that shows at least a single file, its track number, disc number and title as well as the window for Convert>Tag-Filename with the format string that you use.
