Importing classes from previous folder

Right now in my 3D work folder I have a long list of demos and benchmarks all importing classes from my rumblesushi3D folder (package rumblesushi3D), which contains my entire 3D engine.

It’s too long and cluttered, and now that I’m about to start work on my first game, I’d like to put all my publishable work into folders - such as demos, benchmarks, then a folder per game.

The files in these new folders now need to import classes from the same 3D engine that’s now in the previous directory (rumblesushi3D).

The only alternative is to place a copy of my 3D engine folder in each folder, which I obviously don’t want to do.

Say for example, you have a FLASH_WORK folder, in this folder there is a com folder with all the classes you use. All the document classes of your work are in FLASH_WORK, so the same folder depth as com obviously, and are not assigned a specific package.

If you put all these document classes into a folder called archive (created in FLASH_WORK) for example, is there any way to import the classes from the same com folder, now at a previous depth, without renaming ALL the classes in com to FLASH_WORK.com etc etc ?
