To copy an entire mx-project to a USB memory stick it turns out to be many times faster when I Zip the mpr-files and folders (javasource, resources etc) excluding the deployment folder (several Gb's!). Deleting the deployment-folder turns out to be time consuming as well, even when I delete without recycle-bin (shift-delete). How can I get rid of this nasty folder?
You can also create an mpk of your whole project including all resources, but without the deployment folder. Go to File -> Create project package.
How can it be that your deployment folder is several GB? Do you need all the data files. If not, then just create a mpk with one button click.
In a dos box try: rd /S <path>\deployment
This will remove the complete directory structure including the deployment.
