Custom SSIS Component: UnZip Task

In january 2011 I did a post about unzipping files within SSIS with a Script Task. Because not everybody is fond about programming, I decided to make my own UnZip (and Zip) Task. For the actual unzipping I used the well know opensource DotNetZip library.

This UnZip Task is still beta and more unzip features will follow. Please use it, test it and let me know your findings or wishes in the comments below.
The UnZip Task is now stable, but please submit suggestions for new features.

Downloads:
You can download a SSIS 2008 and 2012 version on the download page.

BETA2: UNC path support, cancel variable window bug solved.
BETA3: Various validations added, New option added to store unzipped filepath in variable.
BETA4: Switched to DotNetZip for the actual unzipping * Probably last beta version before official release. *
V1.0: Bug solved that didn't validate driveletters with smallcaps
V1.1: Option added to delete zip file after unzipping it (see properties). Code added for easier upgrading to new release.
V1.2: SSIS 2016 added and now upgradable. Added 64 installer.

Installation
The installer registers the DLL in the GAC and copies it to the task folder of SSIS (example: C:\Program Files\Microsoft SQL Server\100\DTS\Tasks\). After that you have to close Visual Studio/BIDS because it caches the GAC on startup. Restarting SQL Server Data Tools is not necessary.

How add the task the the toolbox (2008 only)
When you open a SSIS project in Visual Studio/Bids, right click the toolbox and choose "Choose Items...". After this Visual Studio will be busy for a couple of seconds!


Right click toolbox

When the Choose Toolbox Items window appears, go to the SSIS Control Flow Items and search for the newly installed UnZip Task and select it. Click ok to finish.

Choose Toolbox Items























Now the new task will appear in the toolbox. Ready to use! Have fun.
