This wiki page is about a path or a file in the Linux file system. Be bold and improve it! Describe its purpose and its use, which program created it and uses it, which configuration settings it might be dependent on, and which Linux distributions typically have this file by default while others might not.

/scratch would usually be a separate partition on a separate, fast disk where reliability if of a lesser concern but performance a boon.

Files and applications to be considered for /scratch:

- distribution packaging (e.g. Gentoo's portage tree).
- off-tree compile directory (the build/ directory in software source tree).
- blender 3D bake files.
- new/ and tmp/ directory in a mailbox directory, as opposed to the cur/ directory which permanently stores the emails.
- per user scratch directories in /scratch/users/ with a symlink from /home/$user/scratch => /scratch/users/$user/.
- video editing.
- /tmp/ => /scratch/tmp/.
- cache files of any application, e.g. within ~/.mozilla/cache.
