Cleaning up a computer today I was looking at the Temporary Internet Files\Content.IE5 folders There were about 8 folders there with random numeral and letter names.
I found many .jpgs there that were of no use like Lucious Lacy, etc.

After I ran CCleaner that took awhile I noticed that each one of these folders were empty of stuff except for one icon.

There were also less folders than 8 now.

Does Windows make these content folder as it needs them and leaves a certain number left for future use?

If it needs more it makes them?

If I wanted to delete the contents of each folder manually except for this one icon is this OK?

What about the extra folders?

Is there a default number of folders that Windows XP keeps there?
