PSoC Creator offers standard way to compress and share projects in few clicks: (1) Clean the project: Build->Clean. (2) Create shareable archive: In the Project Explorer click the Project Name (on top). Now in Main Menu: File->Create Archive Bundle->Minimal. This will create archived project (*.zip). (3) You can further shrink this archived file size dramatically: open ZIP file and delete folder Generated Source. The resulting archive will be <100k in size. It is easy to share/upload now.
