Hi
Would you please help me? I have some questions, what is media cache? I found that there are more than 10 GB files with PEK and CFA extension in media cache folder, can I delete them? Why does After effect create these huge files? Is it normal? Is there any software to search and delete these files?
Appreciate any help in advance.

    So I tried moving my Cache to a different external hard drive and that seam to take via PremierCC and AE CC. However when I import an AE CC composition into PremierCC it creates a .pak and or a .cfa file. not sure why this keeps happening. This only seams to happen when I import the After Effect comps into the Premier CC timeline.

    What  I want if for all cache files to go the external drive. Why is this happening?

    I manually put them in the trash. but I would like to know WHAT are PEK and CFA files and in what instances should they be kept because they are needed.

    If they are thrown away but are needed will they be automatically regenerated by AE??

    you can change the default location of the media cache files in the prefences pull down

    because our artists are "lazy" :-) i put a startup command in
    c:\Documents and Settings\All Users\Start Menu\Programs\Startup

    its a text doucument called "delete_old_cfa.cmd"

    whose contents are

    set FOLDER=s:\aeTemp\Media Cache Files\Cache.MACC
    for /f "Tokens=* skip=100" %%f in ('dir "%FOLDER%\*.*" /o-d /b') do del /f /q "%FOLDER%\%%f"

    on restarting from boot it will keep only the most 100 recent files in the media cache folder .... that will stop those files filing up your harddrive
