OLK Folder???

What exactly is this for?

For instance if I get any file (excel, word, access) on my email (I use Outlook) and I open it and do a "save as " it immediately defaults to Windows --> Temporary Internet Files --> olk3081.

What is that?

It looks like some sort of security. I usually save my files to the “U” drive. Now I have my excel set up so when I open it goes right to my U drive when I do a “SAVE AS”

But when I open any file from an email and do a “SAVE AS” it defaults to the olk3081.

Can I change this?

And what exactly gets saved in there? Not all the excel files I open get saved there. But just looking thru it some files from 2 years ago are still sitting in it.

Thank You
