If a disk is fragmented, this means that the files in your computer are spread out all over the disk taking up too much space. This can be corrected by defragmentation which consolidate all the data.
When your hard disk has just been defragmented, all the programs and files are (to carry the figure) neatly stacked on the shelves where they belong. Every time you use a program of file, and later close it, the hard drive chucks it back on the shelf wherever is handiest - not necessarily, or even usually where it belongs. Before long, all those jumbled files and programs slow down your computer very noticeably, while it "finds all the pieces" to open a program. Defragmenting the disk tidies everything up again. I do it once a week - takes less than 10 minutes.
Go to my computer, right click the C: drive. Go to tools. Click defragment.
Fisk fragmentation, and A.I.R.Y fragmentation.
Disk fragmentation is the process of consolidating data on a hard disk or storage device in order for that device to run better. This process can be done manually on any computer system.
Fragmentation
Changing the structure of a file may or may not affect the fragmentation of the disk. But, in most cases, the computer is going to store the file in the same location after the change.
It's when a disc fragments after extensive use.
fragmentation
Because unused files accumulate space on hard disk and also causes fragmentation of hard disk.
Lots of them, disk clean up, disk fragmentation, that moves the data up front for faster access, check disk for error's, blow out dust from inside

Fragmentation is the result of an inefficient use or allocation of memory space. It is not usually a catastrophic occurrence, but it can cause problems in operating efficiency. In both main memory as well as on disk, data is stored in blocks. The blocks are all uniform in size but the data may or may not be. In other words, data that doesn't fill up the entire block ends up wasting space. This is called internal fragmentation. Alternatively, external fragmentation refers to data that requires multiple blocks to store, but which can't be contiguously located. External fragmentation may cause problems in primary storage, but it's not as big a deal on disk. Data most likely won't load into primary storage if there are not enough contiguous blocks available to house it. A disk on the other hand, will accept data in non-contiguous blocks, but this will cause performance issues. The disk controller will have to look up the address for each block of data, and the moving parts of the drive will have to align in order to use those blocks. This means that seek, latency, and transfer time issues will intensify due to the number of times the blocks must be located in order to read and/or write disk data.
Fragmentation. You can solve this using a disk defrag program.
Volume fragmentation is where the partition volume is physically split across the drive into variable pieces. This is common on HFS and some other filesystems that do not need to be sequential or single-piece, and virtual filesystems. Data fragmentation is when a file or data portion is physically split across a volume, rather than being in a single sequential piece. This is also called 'fragmentation' and can usually be remedied with a 'defragmenter'. It is usually an undesireable state, as it requires longer to load a fragmented file.
