i try to copy from windows explorer to the pak explorer, something like a set of textures. alot of texture files arent being copied because of an error about invalid names...

this sucks for me alot

My guess would be that it is limited to 8.3 length filenames, that means filenames no longer than 8 characters plus 3 characters for the extension.

Master jogi says:
(04:20:27) (@jogi) tell them that there is a limitation on the filename length to 56 chars and thats it

Just use pakscape it'll solve your problem

yeah pakscape owns, or just use .zip/pk3 and winrar/winzip

thanks guys.
