I wonder if anyone knows what the OLK165 file is?

 

It all started with an attachment that I was going to save. The computor wanted me to save it in Temorary Internet Files/OLK165. I started to wonder what that was. I opened the Temorary Internet Files and found nothing about OLK165. I set all the variables to show all kinds of files in the folder - still nothing. I made a search and searched for all kinds of hidden and system files - nothing. Suddenly the search got a hit on a shortcut to OLK165 under "recent". I opened it and found a couple of old attachments resting in peace. The shortcut is still pointing to Temorary Internet Files/OLK165 and it works - but I can't find it. On Google you get 10 hits and they are all file references in the footer of pdf files saying Temorary Internet Files/OLK165/.......etc.....I clear all Temorary Internet Files through Internet Explorer and I still have the shortcut to OLK165 - and still no folder in Temorary Internet Files.

 

What is this?

Are there more folders that are hidden from you that you cannot enter or empty?

Is there a way to make it visible?
