How do I check if the file exists by its relative path? e.g. `existingDir/nonExistingDir/../existingFile` always return false with both, access ans stat

I'm assuming you are talking about *Linux*. In that case you should use the `fopen` function ( <https://man7.org/linux/man-pages/man3/fopen.3.html> ) from the POSIX library (automatically included with all Kotlin Native Linux targets), which will return *null* if the file doesn't exist. Do note that the function does accept a relative path (relative to the *Working Directory*).

Hmm, seems a bit redundant to open a file only to close it right after.

On a side note, is there a way to convert relative path to nonexistent file to absolute? realpath returns null on nonexistent files.

The `fopen`  function technique is slightly cumbersome, however it is very simple to use and gets the job done in a very short space of time.

There isn't anything for converting a relative path to an absolute path. One could work around this by using the `getcwd` function ( <https://man7.org/linux/man-pages/man3/getcwd.3.html> ), and append the relative path to what is returned from the function.

No no symlinks, just trying to build File api for native

Also getcwd doesn't really help as this would still not expand .. and . properly

Everyone seems to be building their own File IO type API for Kotlin Native :laughing: . Waiting for KotlinX IO ( <https://github.com/Kotlin/kotlinx-io> ) to gain File IO support.

Gotta do something to get things moving until that one's ready :grinning:
