A fragmented file is a file that has no purpose or meaning to the computer. So if you have installed a program and then uninstalled it.... many times the computer leaves files on the computer this is called a fragmented file.

A hard drive becomes fragmented when a file that occupies a finite storage location on the hard drive is modified and becomes larger. If the finite storage space on the drive is not large enough to store the larger modified file, part of the file must be stored in another location that is not contiguous to the original storage location. Thus the file becomes fragmented. Now your computer must search for the file in two different locations in order to retrieve it. This is what causes your computer to slooow down.
Ubuntu uses the ext4 file journaling system, which doesn't get fragmented.
Ø Disk optimization process collects file fragments and puts them back together. Whenever the files are changed and saved for frequent times, they become fragmented and the volume is filled with different parts of a single file stored in different locations on a volume, here the optimization process collects all those fragmented files into a single one sunil khadka aicl college
No. File systems can become "fragmented", meaning that not all space is allocated contiguously. When a file is deleted, the space it occupied is marked as being available for future use. When a new file is created, the first available free space is used before free space elsewhere on the disk.

In essence it's a file that is stored on the filesystem in one piece - that is that all parts of the file are stored from beginning to end in adjascent allocation units instead of being fragmented and each piece of the file stored in separate, non adjascent allocation units. As an analogy, imagine a 10 page document. If you place all the pages on your desk in order from beginning to end without anything in between them you could say it's a contiguous file. If you had room to put five pages down in order but then had to put the other five pages elsewhere on your desk, you could say the file was fragmented.

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 Derangement is a tool that rearranges the data on your hard disk and reunites fragmented files so your computer can run more efficiently.
There are two parts to this. One, the information in the File Allocation Table, as the file might be spread over different sectors, not all contiguous if your filesystem is fragmented. Two, this would be the specific sectors at which the data resides that make up the contents of the file. Cheers, Chay
