| How does fragmentation of files occur?
Consider this simple example... Three files(A, B and C), each requiring three blocks of disc storage are stored. |
|||||||||||||||
|
|||||||||||||||
| File B is then deleted...and another file (D) is stored, which requires 5 blocks of storage... | |||||||||||||||
|
|||||||||||||||
| Fragmentation of files has started...File D is split into two separate fragments... | |||||||||||||||
| Now suppose that files A and C are deleted and a new file (E) is stored that needs 7 blocks of disc storage... | |||||||||||||||
|
|||||||||||||||
| Fragmentation is now getting worse, because file E is split
into three different fragments..
...and fragmentation will continue to get worse as more and more files are stored and deleted... But, run a defragmentation program and the file blocks will be reorganised...
