Dvd Shrink Free Download For Windows 7 64 Bit
Celena Holtzberg
I just bought a new computer with a 2TB hard drive that has only a single partition. I would like to divide this into at least 4 partitions, but when I try to shrink the current partition, it says the total size is 1888171 MB and that the size of available shrink space is only 939075 MB. The used disk space is at 40gb right now - why can't shrink it to somewhere around that?
I had the same problem, 500GB harddisk and the shrinking process didn't shrink less than 230GB.. I did the below steps and I was able to shrink to exactly the space allocated by the windows files itself.
WARNING: Re-sizing partitions can also delete your partition (since you are trying to re-size your root partition, this can happen only if you try to re-size externally (without booting into OS)).
Usually Disk management inside Windows won't allow re-sizing the partition because of unmovable system files. But if you try to defrag your partition, you can shrink it beyond the previously limited size, but of course to some extent. But, third party tools can let you re-size the partitions beyond that too. So, you might want to try one of them. I'd recommend Acronis Disk Director / MiniTool Partition Wizard if you are trying to re-size from inside the Windows, else, GParted Live CD is always the best option.
Make sure that you defrag the drive before trying anything. Also, though GPT scheme allows to create more than 4 primary partitions (128), it also requires that you have to switch from BIOS to UEFI booting. So, if you are going to setup multi-OS system, then you must choose the OSs that support EFI boot.
I figured the same problem and finally came to the conclusion:deactive system restore by going into control panel.. system protection and then reduce the hard disk to your desired requirement.once that is done active system restore again.
I would recommend following the procedures given in the article you cite to temporarily eliminate most of the problematic system files, and then use the Perfect Disk program mentioned there to do a boot-time defragment with free-space consolidation. I have done exactly that in the past, and it worked very well. As others have noted, you can have far more than 4 partitions if you make an extended partition and create logical partitions inside it. Don't forget to re-enable changes.
You can decrease the space used by primary partitions and logical drives by shrinking them into adjacent, contiguous space on the same disk. For example, if you discover that you need another partition but don't have more disks, you can shrink the existing partition from the end of the volume to create new unallocated space. That space can then be used for a new partition. Certain file types can block the shrink operation. For more information, see Other considerations.
At the DISKPART prompt, enter shrink [desired=] [minimum=]. Shrink the selected volume by the amount specified in desiredsize in megabytes (MB) if possible, or by the amount specified in minimumsize if desiredsize is too large.
When you shrink a partition, certain files like the paging file or the shadow copy storage area can't be automatically relocated. Also, you can't decrease the allocated space beyond the point where the unmovable files are located.
If the shrink operation fails, check the Application Log for Event 259, which identifies the unmovable file. If you know the cluster(s) associated with the file that's preventing the shrink operation, you can also use the fsutil command at a command prompt (enter fsutil volume querycluster /? for usage). When you provide the querycluster parameter, the command output identifies the unmovable file that's preventing the shrink operation from succeeding.
In some cases, you can relocate the file temporarily. For example, if you need to shrink the partition further, you can use Control Panel to move the paging file or stored shadow copies to another disk, delete the stored shadow copies, shrink the volume, and then move the paging file back to the disk.
If the number of bad clusters detected by dynamic bad-cluster remapping is too high, you can't shrink the partition. If this situation occurs, consider moving the data and replacing the disk. Don't use a block-level copy to transfer the data. This method also copies the bad sector table, and the new disk treats these sectors as bad even though they're healthy.
As far as I know, I need to get the source partition smaller than the target partition before I can mirror. But short of the defrag that I've already done, I'm not sure what to do. I could cull a bunch of programs and reduce the space I'm using, but I'm already using far less than the "Total size after shrink".
The interesting fact which often goes unsaid is that after a partition shrink the minimum size is also reduced (of course, if you have free space, defragged, no unmovable files, etc).
I used this method to successfully shrink a System volume (C:) on Windows Server 2012R2 from 500GB (with only 50GB of actual data) to 80GB. The first time I tried to resize it the minimum size was around 425GB.
When you shrink a partition, certain files (for example, the paging file or the shadow copy storage area) cannot be automatically relocated and you cannot decrease the allocated space beyond the point where the unmovable files are located. If the shrink operation fails, check the Application Log for Event 259, which will identify the unmovable file. If you know the cluster or clusters associated with the file that is preventing the shrink operation, you can also use the fsutil command at a command prompt (type fsutil volume querycluster /? for usage). When you provide the querycluster parameter, the command output will identify the unmovable file that is preventing the shrink operation from succeeding.
In some cases, you can relocate the file temporarily. For example, if the unmovable file is the paging file, you can use Control Panel to move it to another disk, shrink the volume, and then move the page file back to the disk.
You should first check the Application Log as indicated. If the unmovable file is the paging file, you can try to (temporarily) relocate it to another drive, then retry shrinking. However, if there are other unmovable files that prevent shrinking which you can't remove/relocate, then you won't be able to shrink using the builtin facility. In that case you'll need to use a 3rd party partitioning/imaging tool - there exist both free and paid such tools.
As the comments point out, the problem was files that couldn't move during a partition shrink or defrag because they were locked by running applications and by windows. The simplest way to unlock those files is to stop the processes, and the simplest way to stop the processes is to not let them start! Hence, I started looking for a boot time defragment tool.
None of the above worked for me - defraggler showed a couple dozen files at the very end of the drive that I could not move. The only way was to use a tool called AOMEI Partition Assistant - worked perfectly. It loads a preboot app that runs after reboot and does the job - apparently some system files cannot be touched from within the running system.
The posts containing these instructions occupy more space making them seem more important than the tiny interspersed posts containing the simplest solutions. Importance is inversely proportional to size... Also, if something to do with a computer can be written down as precise instructions, a program can be written to follow them and it can be executed by anyone without manual effort...
I have been able to shrink my drive (NVMe SSD) to more or less precisely the size that I am using (from 200 GB down to 140 GB) in 5 minutes including researching the topic, installing this solution and executing it. Most importantly, I did not have to learn anything about typical large unmovable files in Windows which I did not care about at all.
You start up the program, select the partition you want to shrink (I assume it is your system partition/volume C:) then drag the slider to set the desired size. Because the disk is in use, the resizing process will be set up as a Windows PE (Preinstallation Environment) program, scheduled for execution at the next boot.
Disclaimer: If you resize C:, it will require a reboot and the program will be executed one-time in the Windows PE environment which is a reduced windows desktop which you may not find very pretty but it gets the job done.
Obviously, you can use 3rd party software, which I also tried to use, but most of the cases free versions will allow you only to shrink when running the system - for the bootable versions in most cases you need to pay.
I've also tried MiniTool Partition Wizard Free, however like mentioned above, I was unable to shrink while running the system. I've been asked to reboot, however the application froze. Fortunately, I was able to cancel the process without losing any data - system booted normally. One of the suggestions was to use bootable version, which is not free. So I dug more and found the solution.
In my case, I need to look for last unremovable file 3 times and after each deletion, I was able to shrink the partition a little bit. Basically, you jump from the last unremovable file to another, until you reach the desired partition volume. It can take some time but still, you are able to do it without third-party apps.
In my case, following above instructions failed. Somehow I'm still not able toshrink the drive. What worked for me is to restart Windows in Safe Mode (hold shift and choose restart). In Safe Mode, go to advanced and drop to the command prompt. Use diskpart.exe to shrink the drive:
If this doesn't work for you, you may have to either give in and resort to closed-source 3rd party apps (Easeus Partition Manager, Paragon Partition Manger, MiniTool Partition Wizard, PerfectDisk all seemed to be recommended by folks to varying degrees). I like the above approach bc IMO running a defrag is less likely to mess up your current install and make you need to whip out a recovery disc than a partition editor is. And even if you disagree, I would still rather run a FOSS app + a native windows app then be dependent on a closed-source app that might have a limited free trial / require me to fork over $40+ USD for a license so I can perform a one-time operation that Windows ought to have been able to do on its own in the first place (I use Linux most of the time so this is idea is especially not worth the money for me)
