Thanks for the flood of help everyone. After a couple of days wasted learning what someone else already knows but hasn’t divulged, I have answers to my questions. Here they are for you all. Un-hide your User files.
WHERE TO LOOK SAFELY for delete-able files, for Win 7
Note: I run Premier Pro CS5.5 + Media Encoder; Vegas Pro 13; and Cineform; your editor systems may have different names, and put their caches in different places.
Make folder size notes as you search your system, run a process, then look for large folder size changes.
SSD/HDD (C:) >
MediaEncoder Cache >Media Cache
> Media Cache Files
Desktop > whatever not needed.
Program Files > Adobe > Adobe Premiere Pro CS5.5 > cache
PrPro Media Cache > Media Cache
PrPro Media Cache > Media Cache Files > Media Cache Files
User > Public > Anything you don’t want
> User > Anything you don’t want (Un-hide hidden folders); most lost space is in here.
Bottom LH Corner:
WINDOWS icon > search box . . > type ‘disk’ >manage disc space used by offline files > disc usage > delete temporary files.
WINDOWS icon > search box . . > type ‘disk cleanup’ > free up disk space by deleting unnecessary files.
Control panel > system and security > administrative tools > free up disc space > C: > OK > select which files to delete – then > more options > system restore and shadow copies > cleanup – windows update cleanup.
DRIVE (C:) > Users > user >
AppData (HIDDEN FILE) > LOCAL > SONY > VEGAS PRO > 13.0 > *MUX FILES, THUMBNAILS, TEXT DOC’S, XML FILES, AND HUGE DISK IMAGE FILES*
So if you are finished with these ‘Disk Image Files’, delete them and re-gain up to hundreds of GB on your (C:) HDD/SSD.
LAST THING, DELETE ONLY DEFINITELY UN NEEDED FILES FROM RECYCLE BIN.
THEN DEFRAGMENT DRIVE.
TO REDUCE USER PROFILE SIZE:
Change user profile settings:
Search: gpedit.msc and click it > local computer policy > user configuration > administrative templates > system > user profiles > Limit user profile size > enable > set size, and other > apply > OK.
NOTE: You MUST reduce size (remove/delete files) in the user profile list, to below its set limit, before computer will turn off; or have to do a forced shutdown.
Be careful, cautious, and good luck. If in doubt, save all unwanted files, well labeled and addressed, to an external drive for ‘just in case’, and then see if everything still runs OK in usual production methods.
I hope I have helped someone with this info; I’m no expert, so be very cautious with my advice.
