I did a test with a small Premiere Pro CS6 project and discovered that for each change I made to an effect Premiere generated a completely new preview file and stored that alongside the old file ( which was apparently trash at this point )

The reason I did this is that the preview files folder in my main project is **15GB** in size; and I'm assuming much of this is trash based on the above. So I moved it out of the project folder pending deletion and generated a new set of preview files for the project, which which came out around 8Gb - and it seems to work fine.

**My questions is:**

Is there any problem with this method of regaining space other than it takes time to regenerated the preview. I mainly am curious because I haven't seen a reference to this technique anywhere; and also because I wonder why Adobe didn't add a button to purge and regenerate preview files (at least that I've seen) since it's fairly straightforward and reclaims back so much space.

You can delete Render files by going:
`Sequence` > `Delete Render Files`

Or by using third-party programs.
