The .als that are not stored in a project folder have no related Sample, Preset and Info folders, yet there audio and MIDI tracks in those sets.

I always save everything to the default location. I have done a Collect All and Save.
The manual says that Live "Usually" takes care of creating projects automatically (I understand this to be the Project Folder where project related info, samples, presets and the .als files are stored).
For the first ever time I want to send the required project files to someone for a collab but all I can find for this particular project is an .als file of some 216KB in size. This does not make sense since there is both Audio and MIDI tracks in the project so I am expecting something more like 80MB in size. I am puzzled.
