Sort Letter Number

Hello
I don't know how to sort an letter with numbers. I need to create a sequence of these audio tapes from number to the end
Example
t100-panel.mp3
t101-kashouty-haynes.mp3
t102-haynes.mp3
t103-hayes-meherwan.mp3
t104-stevnes.mp3
t10-gim-mcgraw.mp3
t10-gim-mcgraw-alt.mp3
t10-gim-mcgraw-fin.mp3
t11-gim-mcgraw.mp3
t11-gim-mcgraw-fin.mp3
t11-gim-mcgraw-fin_01.mp3
t12-v-small.mp3
t139-hopkinson.mp3
t13-lud-dimpfl.mp3
t140-filis.mp3
t23-adi dubash-a-cohen.mp3
t23-side-b-adi-dubash-minoo-kharas.mp3
t23-side-b-allan-cohen.mp3
t24-a-cohen.mp3
t24-side-a-allan-cohen.mp3
t24-side-b-bill-lepage.mp3
t25-dubash-abzar.mp3
t25-rhoda-dubash-side-a.mp3
t25-side-b-naosherwan-anzar.mp3

It would be a lot easier if you were able to arrange the same number of digits after the initial "t", by inserting leading zeros, so that t100... would remain the same whereas t10... and t23... would become t010... and t023... respectively. If you could do that then they would sort without problems.

If you can't do that then you would need to extract the numeric part (i.e. after the t and before the first hyphen) into an adjacent cell, and then you could sort both columns using that number as the sort field.

Hope this helps.
