I have data like:
  Audio 1
  File 10
  Audio 2
  Audio 3
  File 11
  Audio 13
  Audio 22
  File 20
  Test 22
  Audio 10
  File 1
  File 2  
I need it order first by the text (i.e. Audio, File, Test) and then by number (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22 etc.)
The problem is that sorting it returns something like this:
  Audio 1
  Audio 10
  Audio 13
  Audio 2
  Audio 22
  Audio 3
  File 1
  File 10
  File 11
  File 2
  File 20
  Test 22  
While the result I want is:
  Audio 1
  Audio 2
  Audio 3
  Audio 10
  Audio 13
  Audio 22
  File 1
  File 2
  File 10
  File 11
  File 20
  Test 22  
If they were just numbers (i.e. without the audio, file, test) then I could just sort numerically.
However, how can I sort here first by text and then by number.
