Defrag
They are called FRAGMENTED files
A fragmented disk contains temporary Internet files and unused program files that need to be deleted.YOLO
Disk Defragmentation
I'm not sure what you are referring to by "disk management." There are many utilities to check disk usage, delete files, and manage space quotas.
Contiguous files are files on your hard drive that are all in one place, and not split up ( fragmented ). Sometimes your computer can take one file, and split it into multiple locations on your disk. This is what Defragmenting does. It takes those fragmented files, and puts them together.
Disk compression on commonly-accessed files Files on the hard disk are too fragmented The computer has a virus
Disk Derangement is a tool that rearranges the data on your hard disk and reunites fragmented files so your computer can run more efficiently.
Go to the All Programs in the My computer section or toolbar then click on Accessories then System Tools then click on Disk Defragmenter. THis program is in every computer like Windows and Mac. This program will shrink files for more file capacity and remove fragmented files.
Hidden files are files stored on the disk, but which do not show up when you list a directory of the disk.In DOS, you normally type the command DIR to view the files on a disk. If you would like to see hidden file names, use the command DIR /AH (A=Attribute; H=Hidden).
No diskdefragmenter cannot be used to format a partion. It is used to make all the files to get fragmented. Formatting of partition can be done by using disk management option in the computer management
A disk with data scattered throughout it (as a result of erasing and adding data in the computer) is referred to as being fragmented.
When a program is first installed on your computer, all the files are nice and organised. But as the program is used, these files start to get accessed by Windows. The files are then put back onto the disk in not the same orderly spot they came from. Eventually they are scattered all over the hard drive. This is called fragmentation. A fragmented hard drive is slower because Windows has to go searching for these fragmented files, thus slowing the system down. Running the defrag tool once every two months or so, organises all these files once again.
