SpinZip is a small tool that will allow you to archive files in one of three unique ways.

SpinZip Zip methods:
1. User-specified approximate size.
This method will create create something like "spanned zips" that any compression app (WinZip, WinRAR, etc) can do. However, the key difference with SpinZip is that the zips created are independent of one another unlike a normal spanned set where you need all the zips to extract the files.
2. Specified number of files per zip.
3. Automatically named zips based on filename.
a. Somefile.ext -> Somefile.ext.zip
b. Somefile.ext -> Somefile.zip
