Recreating data1.cab after admin install?

[chaoticyeshua]

After doing an admin install of Adobe Acrobat Professional 8 and slipstreaming the new update, the install folder is ~800mb. Is there a way to repack the files back into data1.cab to reduce the size again? There are a couple others I'd like to do this with as well, but I could probably figure it out if I just had an example to work with. I'm sure this is a n00b question, but I've never done it before and would appreciate some help in doing so, because my Windows DVD with DriverPacks and WPI is approaching the point where it won't fit on one disc anymore Thanks~!
