    No need! Subtract 113 for the source mods in the Steam Apps sub folder in the Program files(x86) directory from the 141 and you don't have too much left to clean up! I simply moved that over to a separate Steam folder and will nuke the rest while leaving the rename main folder intact for scheduled backups while storing complete system images elsewhere. That will be mostly the destination for backing up user account files.

    Well now there's nothing in the Windows.Backup folder and you only find the Appdata under the user accounts where your Local, Local Low, and Roaming folders are tucked away. For browsers other then IE Not Edge which uses IE bookmarks only but others like Firefox, Opera, and so forth those bookmarks are found in the program folder, user profile and bookmarks sub folder when making any backup or importing them from somewhere else. Only if you saw the Apps folder being tossed that wasn't created by the 10 installer but the previous version you upgraded from. 10 no longer has that to find.

    Meanwhile I am now sitting at 350gb used from the 475gb earlier when cleaning the Windows.old renamed to Windows.Backup and can scheduled backups to that one.

    Just to clarify, Appdata isn't a temp folder, it holds important settings for your software.
    I know, but inside the AppData/Local folder, there is a "Temp" folder.

    The %appdata% folder also stores iPhone/iPad backups created in iTunes which can take up lots of GB as my %appdata% folder is over 40gb.

    Each device attached or program will place things generally in a new folder created for that specific item for bookmarks from browsers and VHDs from Virtual Box or VM Player as a couple of examples as well as any MS apps or other 3rd party wares. With any clean install or repair install of Windows the users folder as well as the Program Files and (x86) folders are all packed up in the WIndows.old so you can recover those files.

    That's one reason for leaving the Personal History type box unchecked when going to use an app like CCleaner to avoid seeing the wrong files cleaned off the drive. And also one of the main reasons I prefer to manually nuke anything but the MS temp files the DiskCleanup or "crap cleaner" would otherwise take care of. I know exactly what is getting dumped.

    Do you know for sure what is putting those temps in that folder ? Must be a software on system as mentioned here and you have many Adobe ones are known to put files there.

    Not so great for SSD for such large temps being written and erased.

    I'm not sure what all was using the folder before the cleanup.

    However, I changed the Database and Cache directories for Adobe's software to my larger HDD, they were the last big space takers at over 8GB in total.

    The other 40+ GB, haven't a clue.

    Empty temp folders used to be drive space grabbers many a year back on XP machines but are hardly even noticed now since hard drive capacities expanded big time. The personal history files and possibly anything left behind in the Download folder would tend to chew up more drive space as well as any left over 10 setup files. The DiskCleanup nukes the BT but not WS folder. 3rd party wares tend to leave more folders behind however even when the programs are removed you still see drive space lost.

    I was assuming you had a SSD is why. You would figure those adobe programs only put maybe update info there. Since being great amount is a bit odd in that folder, maybe other appdata folders or programs i have that store temps files goes to Documents, like blu-ray authoring software which i will do like you move to HDD. I know location can be changed in most programs. Identify the files, look at details of them, find were they are coming from.

    While I was 'playing' with OneDrive, i.e. trying to get rid of it, three very similar initialization folders were generated in the TEMP folder. Thus, just exploring what Windows 10 has to offer may create a ton of temporary files.

    I do, my OS is on my main OCZ ARC 100 240 GB SSD.

    Apparently that's the default database and cache folder as well for Adobe Premiere and After Effects, not so much Photoshop... but I changed the directory for Premiere and AE to one on my larger HDD. Been using the computer, my main drive is still at 162 GB. So there may be some temporary files there, but everything for my Adobe software is going to a custom directory on my HDD, which that folder has about 3GB of stuff in it, most likely cached stuff from After Effects comps.
