That's great.  It's neater than keeping four AHK scripts on my desktop for one character, two characters, three characters and " - ".  Thank you.

I've found a script that works for that here:

https://autohotkey.com/board/topic/61066-create-a-folder-for-each-file-in-a-directory/

I just had to change the extension to txt (I'm working with text files) and the regex to "\ - .*"

Sorry if it was bad etiquette to crowbar in a second request.

If you wanted to name the folders after everything before " - ", e.g.,

Achebe, Chinua - There Was a Country
Achebe, Chinua - Things Fall Apart
Adiga, Aravind - Last Man in Tower
Adiga, Aravind - The White Tiger
Alger, Horatio - Bound to Rise
Alger, Horatio - Driven From Home

becoming

Achebe, Chinua > Achebe, Chinua - There Was a Country
Achebe, Chinua > Achebe, Chinua - Things Fall Apart
Adiga, Aravind > Adiga, Aravind - Last Man in Tower
Adiga, Aravind > Adiga, Aravind - The White Tiger
Alger, Horatio > Alger, Horatio - Bound to Rise
Alger, Horatio > Alger, Horatio - Driven From Home

would that be a matter of modifying the above script or is it more complicated than that?

Thanks again.
