Hello,
I personally would not mess with the C:\winsxs folder at all. Mine is at 9.64GB....yes, I have tons of apps installed.
unless you have a second hard drive, it really does no good to put your pagefile on another partition.
True, you don't need the hiberfil.sys file, but check Power Options in Control panel to make sure it is not set for hibernation otherwise the file will reappear.
It too bad explorer can't search for files by largest size. About the only thing you can do with Windows Explorer is navigate to each folder and choose Details View and then click the Size entry.
I don't plan on messing with the winsxs folder.
I know it doesn't do any good to put the pagefile on another partition of the same drive, but it don't hurt either.
The reason I do this is to spread files over my 2 NTFS partitions.
I have a large drive with Win 7 on a 22.5 GB NTFS partition, with no hibernation and a small pagefile my free space is 12.7 GB.
My other NTFS (17 GB) partition is used for the installation files of several large programs like Word, MS Streets and Trips and MS Picture it as well as Portable Firefox and Portable Thunderbird. Putting 1000 MB of pagefile there as well helps spread the load. Free space left is 8.57 GB.
I have a Fat32 partition that has a lot of saved data files as well as my 20 GB of MP3 files.
These MP3 files are playable from Win 7 as well as all my linux disros.
My Fat 32 partition is shared with all the OS's on my drive.
I did think I had disabled hibernation and before using the command line to disable and remove hiberfil.sys
Power Options showed no hibernation enabled?
Anyway after several boots no hiberfil.sys.
One thing Win 7 does poorly is not having a straitforward GUI approach to disabling hibernation like XP has.
You shouldnt have to resort to command line to disable.
