.ram files?

Does vshare allow .ram files to be uploaded? I get the following error message;

"Sorry, uploading a file with the extension .ram is not not allowed."

The allowed file Types are flv,3gp,mp4,mov,asf,mpg,avi,mpeg,wmv,rm,dat

If that is true then why am I able to upload .ram files to this vshare site;

http://www.fetishmotion.com/

and how do I get the same capability for my site?

.ram is not a real video format, it is just a text file that links to ream rm file. So it is not possible to upload .ram file to vshare.

If that is true then why am I able to upload .ram files to this vshare site;

and how do I get the same capability for my site?

Any ideas?
