I uploaded a new function that can read details from zip files, for example the compression ratio and the number of files and folders that it contains. This function is based on a short article I wrote for PowerShell Magazine, Determine compression ratio of compressed files. I have uploaded this function to the TechNet Script Gallery.

Using the this function it is possible to view the details of a zip files, as shown in the following example:

.EXAMPLE
Get-ChildItem -Filter *.zip | Get-ZipFileProperties

Description
-----------
Use Get-ChildItem to retrieve a list of zip files in the current folder and pipe it into the Get-ZipFileProperties function to retrieve information about these files
