Simple Question: Contents of Folder Into Txt File

I just want to take a directory listing of a folder on my computer (happens to be MP3s and about 150 folders) and input it all into a text file. Any ideas on the simplest way to do this? (Not in programming, just me doing)

Thanks!

DIR /S > FOO.TXT

Using /s will perform a recursive search.
To just get that one folder :

Code:

---

dir > foo.txt

---

Or to get that folder and all sub folders, as already stated :

Code:

---

dir /s > foo.txt
