I know nothing about zipping & unzipping files, though I have heard of the WinZip software. I was wondering if it would be easier to zip a file to compress it, before transmitting it from the mainframe to a PC. Of course the file would then be unzipped, after being successfully downloaded to the PC. Can a file even be zipped on the mainframe? If so, will it retain it's original attributes such as lrecl and blocking (eg. variable or fixed)?

The PKZIP/MVS software does retain the dataset allocation attributes (RECFM, LRECL, BLKSIZE, etc.) within the .zip archive file, so a dataset zipped on one system can be easily unzipped on a different system without needing to know all of the details of the original dataset.
