Getting Around Windows 7 "Destination Path Too Long" Error When Deleting Files
Years ago when I started learning VBA for Excel, I was reading a book by John Walkenbach and he compared learning macros in Excel to using a remote control - once you learn it you don't know how you lived without it. I would say that is true of scripting in general.
The bad news is that programming is also like using a credit card, inasmuch as you can get yourself into a depth of problem just not possible without it.
I got experience with that first hand recently when one small programming mistake caused a bit of a disaster on my computer.
