path_sanitize {fs} | R Documentation

## Sanitize a filename by removing directory paths and invalid characters

### Description

`path_file_sanitize()` removes the following:

- Control characters

- Reserved characters

- Unix reserved filenames (`.` and `..`)

- Trailing periods and spaces (invalid on Windows)

- Windows reserved filenames (`CON`, `PRN`, `AUX`, `NUL`, `COM1`, `COM2`, `COM3`, COM4, `COM5`, `COM6`, `COM7`, `COM8`, `COM9`, `LPT1`, `LPT2`, `LPT3`, `LPT4`, `LPT5`, `LPT6`, LPT7, `LPT8`, and `LPT9`) The resulting string is then truncated to 255 bytes in length
