# fallocate

> Reserve or deallocate disk space to files.

|
- Reserve a file taking up 700 MiB of disk space:
|
|
|
|
`fallocate {{[-l|--length]}} {{700M}} {{path/to/file}}`
|
|
|
|
- Shrink an already allocated file by 200 MiB:
|
|
|
|
`fallocate {{[-c|--collapse-range]}} {{[-l|--length]}} {{200M}} {{path/to/file}}`
|
|
|
|
- Shrink 20 MB of space after 100 MiB in a file:
|
|
|
|
`fallocate {{[-c|--collapse-range]}} {{[-o|--offset]}} {{100M}} {{[-l|--length]}} {{20M}} {{path/to/file}}`
