After six years away from Macs and using a PC, I have a ton of files I have created there. Now, I am awaiting delivery of a new 2.6 GHz iMac with 2 GB of RAM, OSX Leopard, and a 320GB HD. My question is, are any of my Win documents (not applications) going to not display on the iMac? Specifically, I am concerned aboout .wmv, .avi, .mpeg2-4, .jpg, .gif, .wav, .mp3, as well as the usual .doc. .pps, etc. files. I have all of these on an external USB HD, so connecting I don't think will be a problem, but I would hate to lose my videos that I have made. A lot are of family events and my wife would be "slightly irritated" (married men know what I mean) if I lost those. I know a lot of improvements have been made on Macs the 6 years I have been here in Brazil, but sometimes "progress" is not all we would like it to be.
