Zipping and Unzipping Files in Pega Robotics
If you ever have the need to zip and/or Unzip files within a Pega Robotics solution, here are a few scripts that can be used to do just that using a dll shipped with Pega Robotics Studio.
- Add a new script component to your global container.
- Right-click the component and add a reference to the ICSharpCode.SharpZipLib.dll located in the installation directory for Pega Robotics Studio (or the plugin).
3. Finally, create all four scripts using the attached text files.
4. The _CompressFolder script should be added first as it is used by one of the others.
When zipping a file, drap the ZipFile method from the script into your automation. It accepts three parameters;
- zipFileName - This is what you want to name your resulting zip file.
- password - This can be left blank, or you may supply a password.
- folderToZip - The path to the folder containing the file(s) you want to zip. This will not zip an individual file as written, however you could possibly modify the script to do so if required.
When unzipping a file, drag the UnzipFile or UnzipFilePassword method out to your automation. These methods are identical except that the latter would be used if the zip file were password protected. The parameters for UnzipFilePassword are;
- archiveFileNameIn - The full path to the zip file
- password - The password for the archive
- outFolder - The directory to unzip the file to
The parameters for UnzipFile are;
- zipFileName - The full path to the zip file
- targetDir - The directory to unzip the file to

ICSharpCode.SharpZipLib.dll does not appear in v19/v22 install directories anymore it seems, and this is the only piece of 'documentation' findbale for opening passworded zips. The provided tools in v22 do not seem to support passworded zips.

@PhilipG1165 In 22.1, we have added native methods to the Palette to zip and unzip files, so no script is needed any longer for non-password-protected files.
Also for 22.1, we removed many third-party assemblies that were no longer required by the product. This script will still work in 22.1, however you would need to acquire the library on your own. It is open source, so it may not require a license to use. There are other third-party options as well since this is not a feature supported natively by .Net (or Windows). If you do want to use a third-party assembly, be sure to place it in %AppData%\Pegasystems\PublicAssemblies.
If you have 7-zip, then you can easily do this using a Process.Start method. You would set the fileName parameter to the path to 7z.exe (in my case it is C:\Program Files\7-Zip\7z.exe) and the arguments you could acquire from the link below. Here is a simple example. Replace the parameters including the curly brackets with the appropriate values.
x {PathToZipFile} -p{password} -o{extractDirectory} -y

I am certain you can do this with most third-party zip utilities as well if you did not want to use a C# script to accomplish this.

Is there any reason that Pega22 only has mehods that work for non-password-protected zip files?
Is there a plan to add an option for files with a password?

I don't believe that this is a feature natively supported by .Net. It would require a third-party library to accomplish. That is likely why it is not something included in the methods available in the Toolbox. I am unaware of any immediate plans, but this is certainly possible using one of the methods mentioned in prior replies.
