General directory scanner

[ErosOlmi]

Generic script illustrating how to loop inside directories to search for files.
A general purpose DoTheJob function can me personalized.
In this case function is just printing file name, date and number of days since last write access to file and today.

Tip: execute the script once and than execute again. This will give you the idea of what is caching on hard disks usage.
On my system it can takes something like 1 minute the first time and 10 seconds from second time on.

Thanks Eros these are so handy and powerful.

You should make a master compressed version of Eros's super duper scripts!!
