The system partition is occupied by hundreds of megabytes of space for no reason.

Q: My system is Windows XP. When I transfer all the files in the F drive to other partitions, the displayed space is a few hundred MB in its properties. Why is this?
A: This is probably because you enabled the system. Restore & rdquo;, and & nbsp; system restore & rdquo; record file in the partition takes up a few hundred MB space. You can right-click on “My Computer", select “Properties"→“System Restore" in the "Available Drives" list, select Partition F, and then click “Set” Button, adjust “ system restore & rdquo; available space. If you don't want "system restore" to occupy the valuable space of the partition, you can also tick "‘system restore & rsquo;” on this drive to turn off the "system restore" function on the partition.
