I am trying to shink Windows 7 OS partition C: but cannot shrink as much as I plan due to unmovable files. I have tried Windows own defrag tool before but it does not move files that are unmovable. Here are some ideas I have learned from previous posts, and I hope at least one of them will work and wish to know the detail how to do:

1. Inspired by this post, which suggests backup C:, then delete C: , create a smaller partition, and then copy the backup to the smaller partition. I was wondering if anyone here can confirm that Windows 7 will still work in this way? What reliable tools can be used for backuping the system, and deleting and creating partition, and then copying back the backup in this method?

2. I am actually trying another way suggested in this post. I have identified what unmovable file currently stop further shrinking:

   \ProgramData\Microsoft\Search\Data\Applications\Windows\Projects\SystemIndex\Indexer\CiFiles\00010015.wid::$DATA

   If I understand correctly, the file belongs to Windows Search. Can I set up somewhere in Windows system settings to temperately eliminate the file and similar ones (because there are many similar files under the same directory which I guess will also stand in the way of shrinking and unmovable by defrag)?

3. Any other idea that might work will also be appreciated.

Thanks and regards!
