I hate winzip, why winzip?? why not allow it to open with the regular default zip program?? I've tried to download winzip, and it screws up my computer, and is always asking me to purchase to stupid program! I don't want to purchase this when there are other programs including the default one that you don't have to pay for!

Because FligthSim.com and AVsim only accept zip files. It's not the regular because I dont have winzip, I use squeez plus It is so easy to use get and use winzip...

I too upload my repaints to flightsim.com and AVSIM library, but I use my default zip program to zip my files. Anyone can open them with any zip program, but zipping them with winzip, you can't unzip unless you use winzip, and that's just stupid!
