I dont know if someone has posted this already-- but this is an "advanced" mac question (i think)... i have a broadband connection at work, and dialup at home. So, it makes sense for me to download my files there and transfer them here. The problem is, at work i use windows2000, and at home i have macOS 9.1 and os X 10.0.4.

now for the question. How come all my .sit files are corrupted and all the .dmg ones arent?? How do i uncorruptify my .sit files?? I have even tried downloading .sit's within the macOS and have had a lot of problems with them. I currently have the latest version of Stuffit.. PLEASE HELP!!
thankyou in advance
