My brother has been asking me to help him because he has no space on his c: drive, so I install ccleaner and it did help out. But after a week he told me he is out of space again. After testing other apps, nothing would clean his drive. So I installed a disk analyzer and noticed that his appdata was very big.
After checking it out, it was a folder called "media cache file" (if i'm not mistaken). Adobe says its a tmp folder for lots of adobe products. my brother used Adobe Premiere and we noticed it was full of files with the names of his videos he has edit over a year. So reading adobes site:
http://help.adobe.com/en_US/PremierePro/4.0/WS741BE3C1-41CC-4e00-BCA2-E1DC068001CF.html
I could clean it out without problems, its like a backup folder which was at 40 gb of space. I used the clean feature but still noticed files in the folder. Some other adobe apps puts there files so manually deleted them. Its at:
AppData/Roaming/Adobe/Common/Media Cache Files
Theres another folder called "media cache" which is also cleaned out if i'm not mistaken.
AppData/Roaming/Adobe/Common/Media Cache
My suggestion is add this folder to application feature in ccleaner. I have read other forums and everyone says it ok to delete it. I think after ccleaner did its work and 40 gb just appear on your drive, they would surely have a smile
I hope you guys can analyze this and thank you for a great product.
