Hello

Is there anyone who know if I can use CRW files ?
I tried many programs but none of them recognise these CRW files. Does it mean i cannot use them?
ACDSEE 4.0, Bibble 2002, none of them can handle these files. Is there a way to make TIFF or any other files from them?

I saw some software from the Canon site but none of them can be used under XP or Win2K.

Thanks
