How to split a volume in Windows 10 if non-movable files get in the way?

Question

Windows

I wanted to put 7ku next to the 10th. I decided to bite off half of the disk (the total volume of partition C is 900GB). She gave me a bite of only 300 GB, referring to non-movable files. Googled it, deleted the paging file, restore points, turned off hibernation and 80 (!) GB became available, instead of 300. I have never seen such impudence. Please advise how to bite off half of the partition without killing the system. I read about acronis, but the reviews are not laudatory.

Answer 1

Swap file, hibernation, restore points - delete.
Defragment
Compress.
Then return everything back.

Answer 2

I faced the same problem, and all the previously given answers did not help me directly solve this problem, but they pushed me to the correct solution.
On the advice of hint000, I found out which file interfered with compression. It turned out to be a file whose name ends in ::$SECURITY_DESCRIPTOR . If I understood everything correctly, then these files are created due to the Win + Linux dual boot for the following reasons:
If you mount an NTFS partition in Linux not via ntfs-3g
If you have not disabled fast startup and hibernation in Windows (according to Artem 's advice )
How remove SECURITY_DESCRIPTOR?
To do this, you need to reset all rights from the files
I didn’t do it on the system partition and I don’t know what will happen if I do it on the system partition
In the root of the desired disk, you need to do:
icacls * /T /Q /C /RESET
After that, all free space became available for compression

Answer 3

Neither defragmentation nor disabling paging, etc., helps.

Answer 4

You forgot one more non-movable thing. There is something like a copy of the MFT in the middle of the volume usually lives. Windows won't move it. Use third-party programs to resize partitions. I will not advise specific, I did not follow what is relevant now.

Answer 5

In my DiskDefrag 9 program from Autologics, (it shows data clusters) right in the middle showed a non-movable file. It turned out to be pagefile.sys, this is the swap file, I turned it off (how to disable / delete it is on the Internet), then I was already able to divide the disk through the Windows utility. Then it's best to plug it back in, unless you have 32gb of RAM.

Answer 6

Nothing helped me either, neither disabling protection, swap file, crash dump, etc. 2 hours tormented. It turned out that the unmovable file was Eset antivirus. Took it down and it worked :)
