[//]: # "NOTE: THIS FILE WAS AUTOGENERATED FROM README.md"
# Ignoring unmodified files
_Black_ remembers files it has already formatted, unless the `--diff` flag is used or
code is passed via standard input. This information is stored per-user. The exact
location of the file depends on the _Black_ version and the system on which _Black_ is
run. The file is non-portable. The standard location on common operating systems is:
- Windows:
`C:\\Users\<username>\AppData\Local\black\black\Cache\<version>\cache.<line-length>.<file-mode>.pickle`
- macOS:
`/Users/<username>/Library/Caches/black/<version>/cache.<line-length>.<file-mode>.pickle`
- Linux:
`/home/<username>/.cache/black/<version>/cache.<line-length>.<file-mode>.pickle`
`file-mode` is an int flag that determines whether the file was formatted as 3.6+ only,
as .pyi, and whether string normalization was omitted.
To override the location of these files on macOS or Linux, set the environment variable
`XDG_CACHE_HOME` to your preferred location. For example, if you want to put the cache
in the directory you're running _Black_ from, set `XDG_CACHE_HOME=.cache`. _Black_ will
then write the above files to `.cache/black/<version>/`.
