This is kind of abstract, but pretty neat if you need it.
Can't say much about the site design, but the file linked from that page does a cool thing... you have to 'enable macros' to use it... understood if you are paranoid about that but I've used it a few times now with no problems.... anyway...
The excel file asks you to browse to a directory on your computer, and it imports the file info - name / date created / date last modified / date last accessed.
I needed a spreadsheet containing a whole list of print ads I am working on and this was a really quick way to get them set up!
I am assuming you could use it in a folder of web files, too - it asks if you want to 'include subfolders?' and if yes, it lists out the files really nicely by directory. Cool stuff! (if you like that sort of thing)
