WinCVS and binary files

[KM]

Hi All

This might not be the right group, but perhaps someone is able to help
me.

I´m currently using WinCVS 1.3 and have found that it is not allways
able to recognize whether the file is binary or text. This has caused
some files to corrupt, because (in my opinion) WinCVS only commits the
file header and not the entiry file.

Is there anyway to force certain file extension to be binary. I´ve
looked thru http://www.thathost.com/wincvs-howto/ - and it doesn´t look
like it, but I could be wrong.  
Any comments/sugestions is greatly appreciated

TIA
Kaare
