I'm trying to shrink my C: partition, and I'm following the advice in this question:

How to shrink Windows 7 boot partition with unmovable files

I have the same problem of unmovable files, and I've disabled already System Restore, Pagination, Hibernation... and still can't shrink anything my 350GB C: partition that actually only uses 80GB.

I'm following the Event Viewer method explained in that question, I use the shrink option in the Partition Manager and then check the Event Viewer -> event 259.

That event throws this message:

Diagnostic details:

  • The last unmovable file appears to be: \Users\Albert\AppData\Local\Microsoft\Windows \Temporary Internet Files\0AYu0utzFxpSlQ:cJa3UJYivVxT5eSKOsolvCA:$DATA
  • The last cluster of the file is: 0x56f8b5b
  • Shrink potential target (LCN address): 0x159fe49
  • The NTFS file flags are: ----D
  • Shrink phase:

The problem is that when I go to that folder (Temporary Internet Files) there's nothing there (I already deleted them from IE), but I have the folder options to show all hidden and system files.

Is it a super invisible file? If not, why do I get that message in the event viewer?

Any help would be much appreciated!

try unplugging your internet connection and restarting to make sure no programs attempt to build new temporary files. – Jeremy W Apr 4 '12 at 0:38
along with Jeremy's suggestion, perform a clean boot and then shrink while clean… – Moab Apr 4 '12 at 0:47
to Jeremy and @Moab thank you for your suggestions, I've tried both things without any success. When performing a clean boot, I can't perform a shrink command, I get an error. First it said that the Virtual Disk Service wan't available. I performed another clean boot activating that service, but when doing "shrink" I would get another error that the device is not available or something like that... any other thing I can try? – Albert Apr 4 '12 at 1:23
Good link there showing possible ramifications of shrinking, so i do not have to mention having a backup. I find that it is a waste of time to try and unlock, unhide, and defrag to be able to shift a partition around. Acronis disk director, and Easeus home version, will do these moves at boot before the files are locked. There can be files that are just wrong :-) charachters that basically cause failure, there are even protection schemes that I have seen purposfully create a corrupt filename to lock the file. There are files that the system simply will not show. Defrag at boot, move at boot – Psycogeek Apr 4 '12 at 2:04
Do not use Explorer to view system files - it lies endlessly. Use "dir" with the -force parameter in powershell, or the equiv. in cmd.exe. You may be surprised. Ditto using a boot-time app to move stuff as necessary. Some defrag apps can "compactify" the file system that way, then you can use Disk Manager to shrink. – kreemoweet Apr 4 '12 at 2:17

I finally decided to forget about the Windows Partition Manager and go with EaseUs, and everything went actually really smooth and now I have my shrinked system partition and used the extra space to install Linux Mint 12. I have both on a dual boot and everything seems to work fine so far.

Thank you very much to all the people who gave me some advice, it was really helpful!
