Case: you have more than 100 scripts in your maya scripts folder, cluttered, and now u're confused to filter those which are not used.
example: u have 15 scripts for modeling, 55 for rigging, 20 for texturing, and 30 for the rest.
solution:
- create a folder based on the category ( ex: modeling, texturing) it can be anywhere.
- put relevant scripts to each folder.
- go to my computer, RMB and click properties, then follow this.
- what it does is actually set custom path, because maya's default script folder is in your 'my document\...'
