Lite portable OpenOffice anyone?

Actually using only one OOO application only saves about 5mb.

Unfortunately, the last version of Open Office that was separate apps in the way that you mean was StarOffice version 3, back when it was StarDivision that published it, a small German company in the late 1990s.

They merged it all into a single application with different looks for different apps in version 4, which is still before Sun got interested, bought them out, and released the source code to the open office project.

There is little or nothing that you can actually remove from the bundle just because you don't wish to edit some file types with it, so, while I wish that you could do exactly what you suggest, having perhaps a common module, and installers for the components that you want, it simply isn't possible with OpenOffice.org. At all.

It's mentioned right on the OpenOffice.org Portable homepage:
https://portableapps.com/support/openoffice_portable#custom_install

While you can remove stuff like help files and python, you can't remove things like Calc, Impress, Draw, Base, etc as OpenOffice.org is one program (unlike Microsoft Office which is separate programs with a chunk of shared libraries).

In the beta thread, it was mentioned that he made a lite version that was considerably liter. I'd love to see it released.

I do use all of OpenOffice.org but I don't want all the components to show in the PortableApps menu. Can I remove the .exe files for those components? On the rare occasions that I do want to use things like Math, Base, Draw and Impress I'll open a new document from the OOo file menu.
