I often got tired of adding one file at a time

However, I prefer this method because there is no file size limit for certain types of files.

How do I upload files to the assets (Media)

How to add / delete multiple files (images) to the assets (EDIT: AIA max 30MB) with 7-Zip or winRAR:

This is an old post, so today the aia size limit is 30MB or 50MB for http://code.appinventor.mit.edu/#5303034247874286148.
