[Scilab-users] find all files of specific type on hard drive

[Claus Futtrup]

Hi Philipp

To extend on the proposal by Denis, for Windows there is the DOS 
commands, like:

DIR /S /B path\*.txt > result.lst

It will traverse all subdirectories and with the pipe generate a text 
file with the result (replace 'path' with your real-name parent folder 
path). The result.lst contains a list of all files (one per line) with 
their complete file-path-names.

Best regards,
Claus
