I some time back downloaded a file relating to linux teaching material from a p2p network (maybe torrent)
The file has .rar extension and the size of the file is shown to be 114 mb
Whereas when i extracted its contents to a folder, the folder's size is reported to be just 20 mb
I wonder why the rar archive file size is reported to be so much. Recovery record is also present in the archive, but i dont think with a recovery record being put into it the file size increases to 5 times the original.
Could there be something else also contained in it which is not visible normally.

Can someone throw some light on this.
