C# - Recursive File Search

Well, I finally got around to rewriting my program to manage the portable programs I use on my external drive, and as part of it wrote my own recursive directory listing function. Ive alwasy liked the idea of automating portable applications handling, and so earlier this year I wrote a Delphi program that read a list of .bat files and gave a nice menu to select and run them, but it was a complete hack job and not really what I was aiming for.
Now that I have written a recursive file lister I can begin actually doing what I aimed for in the beginning. The planned fetures are:

• Easy to generate lists
• Multiple list support
• Easy to modify single items
• Option to open a listing with another program
• Drive letter adjustment (for your external drive)

Hopefully this will be ready before varsity starts next week.
