Windows 7 - backup files

been doing a well overdue spring clean and found some back uyp files that have got me a bit confused.
there both on the same drive one is just a symbol and says GC-PC and the image is of a HDD a CD and a green arrow pointing down towards the the disc, properties of this say its a file folder and the size is 78.3GB
the second is a folder and is named "WindowsImageBackup!"
and the size of this is 59.9GB
obviously for space reasons i would like to get rid of one of these they seem to be different backups but are they linked in some way meaning if i delete one the other wont work?

thanks

sorry for posting in the wrong section,
anyone got any ideas for this?
thanks

Take look at this post.

How to properly delete Windows 7 backup System Image - Windows 7 Forums

WindowsImageBackup is the name Windows 7 Backup and Restore gives to a folder where it saves the backups and system images. It contains individual subfolders for every image and backup.

Follow the link Theog gave you if the images and / or backups were created with another computer. If they were created with your current computer / Windows setup, read this tutorial: Backup User and System Files - Delete Backups

thankyou guys
that link youve posted theog dosent work m8.
i think what it is, the folder that says WindowsImageBackup and contains individual sub folders like youve said Kari is from a different setup on another HDD
and the image's for the setup im on now is the icon that dosent open up like a folder, if i double click on it i get a pop up giving options to do a windows back up.
