Empty file is 21MB

Involute

While tracking down another problem with a model I selectively deleted geometry to reduce my file size, which started at about 23MB. I ultimately got to the point where I'd deleted everything (<CTL> a <DEL>), and the file was still 21MB. I thought maybe the textures I'd imported from photos were causing the bloat, but they total only about 4MB on disk. What else could be causing this? Thanks.

Component definitions? Even if you delete them from the model space they are still part of the file unless you purge unused components. This is a great benefit when you inadvertently delete components and don't catch it until later but they can cause file bloat if you don't purge the unused components you really want to get rid of. After purging unused components, purge unused materials. Or go to window>Model Info>Statistics and click on Purge Unused to hit everything.

Well, my stats don't show any components. If I purge unused materials I save a couple MB. If I then purge all unused I save another 13MB, but I'm still at around 6MB, and I don't know what was purged. Stats show I still have 112K edges and 10K faces, even after I turn on hidden geometry (which reveals a single line) and delete everything.
