Many programs are available to check for spelling mistakes or wrong grammar.

This will output a list of all the files and directories (and subdirectories) in the folder to output.txt. Then open output.txt in Word and use Word's spell checker.
Could you not simply pull off a list of folder names into a text file and run a spell check on that file?
This VB code snippet will list all folder names on a computer, at the moment it writes to the screen but piping the output to a text file should get you a full list. Then simply open that list in a word processor and run a spell check.
