Question

What does "Purge" do?

Hello,

   I've been using After Effects for a tiny while, I've doe a few simple things in it. I've also made my intro for my videos, which turned out well, buut one thing I can not find  the answer to! ANYWHERE!

I've been told to "make sure you purge your stuff", and I've heard it has to do with the RAM Preview option. But what does "Purging" actually do?

     Thank you for answering my question!

Thanks,

Purge frees up memory, it does not clear the disk cache. Your ram previews and audio previews are stored in memory. Basically everything in the timline with a green line over the frames is stored in memory. If you're also getting a blue line then you have disk cache turned on.

If you have AE configured to use Disk Cache in the preferences then you should go in anc clean in out on a regular basis.

You can clean AE's disk cache by going to Preferences > Media and Disk Cache, then click the Empty Disk Cache button.
