what is this for?

in CC 1.05

inside folder named "metagames" there are about 400 MB (400?!?!? ) of files

what is the function of the voices "Autosave" "BrainLiq" "Test"??

In CC 1.0 there was not all this material!

...

Metagames is the campaign. Autosaves makes the folder bigger. You played the game, now the folder has increased in size.

oh thank you

so, i never play campaign, i only play in skirmish defense mode

so can i delete all file in "metagames.rte" folder without having the game crashed?

No, deleting one of the default folders will make the game crash on startup. If you want to, you can delete the autosave pictures inside Metagames.rte, but if you delete anything else you might make the game unplayable.

i saw in CC 1.0 there was only the file named "index.ini"

so i tried to delete all file except index.ini and the game runs well

Yes, it works without the autosave.ini too. Both the images and autosave.ini are just saves, so deleting them isn't a problem, as long as you don't delete index.ini.

now the game's total size is about 50 MB

thank you for instant answer to my questions

No problem!
