+Some Fix functions can refer to files on your system. Paths are by default relative to the current working directory. Paths can always be stated in UNIX style - even when running Metafacture under Windows. If using Windows style you have to escape the backslashes (`C:\my\path` > `C:\\my\\path`). If you want to address files relative to the Fix file add `.` as directory (`./myFile`). To address files relative to the location of the executed Flux file, use the predefined `FLUX_DIR` variable, but you need to add the `*` to the `fix` command in the Flux (see above). You can also use `..` for the parent directory.
