Holy cow! Does the AssetCache floder content just keep growing forever? 
I have a HUGE number of folders in this folder. It slows down all kinds of things that take forever to read that tree and other things just choke on it altogether.
Is there a way to clear this cache?
Is it OK to just delete all the contents of this folder manually?
Does Flash have some way of automatically houskeeping this?
Thanks for any help.
CCleaner is alright (Yes, I realize the age of the thread; however, this problem is still (ever) present). Just btw., fortunately, they do release a light version of their (free!) software, "CCleaner - Slim" @CCleaner - Builds
Anyway, the Adobe Flash Player AssetCache folder issue remains unchanged... The location is used to store cached content!.. Just, not exactly sure why the answer had included a link to a off-site thread /forum.
In Windows, you can use the keyboard shortcut, from the Run... dialog (Windows key + R), type: %appdata% and it'll open up the location in Windows Explorer (in your -user- profile folder):
C:\Users\Home\AppData\Roaming
... From where you can access /check the two (2) folders containing the cached data, three (3) actually!.. 1) C:\Users\Home\AppData\Roaming\Adobe\Flash Player\AssetCache and 2) C:\Users\Home\AppData\Roaming\Macromedia\Flash Player\#SharedObjects (Everything can go!..:)) & 3) C:\Users\Home\AppData\Roaming\Macromedia\Flash Player\macromedia.com\support\flashplayer\sys (For example, you could choose to keep the "settings.sol" file, there).
^^ And delete the folder(s) within AssetCache, one(s) marked with numbers only... That'll be the cached folder(s). 
The files you're talking about are called Local Shared Objects, or "Flash Cookies" in the colloquial. If you clear your browser cache, we'll blow LSOs away at the same time. If you want to prevent accumulating them in the first place, Incognito/Private Browsing Mode is always a good approach. Everything gets stored in a temp directory that gets blown away when you exit private browsing mode, and the content runs normally. There are also preferences to explicitly block the storage of local shared objects (and there are totally legitimate reasons for content to create them), but the content may not run normally if it depends on LSOs.
Similar to cookies, LSOs are generated by the content that you're viewing, which might be ads, or might be useful content. Flash-based games will often times store assets like sprite sheets and graphics caches to ensure that the games start quickly and perform well, instead of downloading all assets each time you play the game.
Either way, there are a number of controls available to you.
