Here is my workflow.
(I'm a teacher)
I scan student work into an "action folder."
I use textexpander to rename the files with the date and subject and then the cursor is set at the end where I type in the student's name. So it might be named. 2012-25-05 reading Sam.
Hazel watches the action folder folder and then puts this into a folder by subject. So that last file would be put in a folder called "reading".
What I would like is for hazel to create a subfolder for "Sam" or any other student name I type in. Is there any way it can create a subfolder, but only name that subfolder using part of the filename, in this case, a student's name?
