## FAQ
|
||
|
|
|
||
|
|
#### Why doesn't it have a cleanup method?
|
||
|
|
|
||
|
|
Temp files will be periodically cleaned up on macOS. Most Linux distros will clean up on reboot. If you're generating a lot of temp files, it's recommended to use a complementary module like [`del`](https://github.com/sindresorhus/del) for cleanup.
