AstroZip offers a simple, alternative way to create zip files. The basic idea is that we tend to collect large amounts of AVI files when capturing astro images with webcams. This can easily become tens of gigabytes in one evening. I want to save all my captured data and burn the original files to CD-R disks. Processing techniques are constantly improving, so keeping the raw data is important. But since the amount of data is large, lossless compression is needed. By using WinZip, I can compress all files without quality loss in one operation, but the result is much too large to fit on one CD-R. The alternative is then to zip each file, but that is a laborious task. AstroZip was created to help solve this problem.

With AstroZip it is easier, you can use the "Keep Individual Files" option, and create a zip file for each file in the source folder automatically (but files with same name will be put in a common zip file), and the output is stored in the target folder. The target folder can be a mapped network disk, so the program can also be a nice way to copy compressed data across a network.

Since the resulting files are of reasonable size, they are easier to pack on a CD-R.
