What is the file MP01 used for

Hi All

Have BE2012 SP3

D:\TEMP\Backup Exec contains three folders

\MP01

\MP02

\MP03

Each of these folders contain what looks like a shortcut.

If I try and open any of these files in MP01 02 or 03 then I get an error message.

My SDR job which runs on the backup Server is failing because it cant find these files either.

Any Idea what they are ? Can I delete them on the basis that they dont exist ?

Many thanks for your time
