Most of the Windows Mobile softwares comes in executable file which could be double clicked and installed directly, but some of the
applications just come in a CAB file which should be copyed to the device and installed from there. This copying could be a little
complicated for a person not so aware of software installing and such. Here comes some new solutions for this problem. The first one is called
CABviaActiveSync. This great freeware applications adds an option to your Windows Explorer context menu labeled "CABviaActiveSync". After having CABviaActiveSync installed at your system you will be able to just right click a .CAB file and select "CABviaActiveSync" from the dropdown menu to have it copied and installed at your device. Pretty useful ah ?

The second option i would like to show was originally created for
Windows Mobile Smartphones only but i think it should be working at all the Windows Mobile devices. It's called
Sp Cab File Kit and its a little more advanced than the "CABviaActiveSync". "Sp Cab File Kit" supported extensions are standard Smartphone CAB, setup INF, at setup XML. You can analyze, extract or just install a .CAB file by just right clicking on it. here you can check out a
demo video of how "Sp Cab File Kit" could be used.

Both options are useful but i recommend "CABviaActiveSync" for beginners and "Sp Cab File Kit" for more advanced developer users.

OK I give up, How do I install the freeware programs to my Mobile Q? They come as a zipfile and I only see a _setup.xml file.
