hello !

Is there any software freely available to create .ctg files from .pgn databases ?

You want to create a Chessbase opening book (.ctg) or a Chessbase database (.cbh)?

I'm not sure of what you are looking for, Laurent. But here's a web page with loads of chess utilities :)

Hope it helps! Bonne chance!

an opening book (.ctg), but for some reason the import function of my old shredder doesn't work ?!

What version of Shredder / Fritz is it?  Was it a pirated copy, or one you purchased new? 

This was a purchased copy - it's shredder 7. I think the problem might be because I installed the program on an external disk rather than the main (C\:) disk.

I've already had problems with fonts...

edit : I re-installed it on the c:\ drive and it works fine... Thanks everybody who helped - thank you Angelo for the nice link -

No problem, mate! :D I wasn't much help but I am surely glad to hear you solved your problem... :D

PS: I should start working on an opening tree as well, I just got my arse handed to me on my favorite line... :S

Oh, super cool!  Yea, I have had similar experiences with other programs.  If it isn't on the C: drive, certain features don't work right.  Considering this, it's weird that they even give you the choice lol.

Glad it worked out man!  :)
