dat and wad files

how can i associate a wad file with dat file?

example: what i want to do for S1CT04.dat open with another wad file and not with imola2001.wad ???

thanks

If you mean you want it to use the imola.wad because you want the tracks to be in a different order, then go get TSM, trust me, it will make your life so much easyer.

yes, i use TSM :D. but i would like to know how i can do that. like in 2005 trackpack
