file lister

[zedd151]

lister is a program that will list (seperately) all files and folders in a selected drive, directory or folder.

It is not a command line tool, nor does it have a GUI.
It simply does its sole job, announces when it is finhed, then exits.

Upon running the executable, a Browse for Folder dialog appears. Select a drive, directory or folder.
Output will be given in two files namely files.txt and dirs.txt in the folder where the program is located.

files.txt will list all files in the selected drive, directory or folder including the full path name.
dirs.txt will list all the subfolders in the selected drive, directory or folder including the full path name.

Once the program finishes listing all the files, a message box announces "done!".
After closing the message box, the program simply closes.
