Hi
You're welcome. Glad to help.
That subfolder builds based on Flash sites you visit. The files work like browser cookies. You can clear out the subfolders as you wish. I suggest leaving alone those sites you often visit.
Great you had a Time Machine backup. I find it quite a useful tool when looking back in time for older files.
I maintain both a Time Machine backup and a bootable clone of my HD on two partitions of an external HD drive. The bootable clone (created using
SuperDuper.) I update before any OS change requiring a computer restart. This way, if something goes awry I can easily restore the system to its earlier state. While Time Machine can also restore an entire HD, it doesn't do it as efficiently or quickly.
