[BUGFIX] Fixes the crash when the folder doesn't exist

For some reason if the path doesn't exist, program crashes. To prevent this, the path has to be checked

Branch updated — SUBPROCESS_ENCODING removed, crash fix kept

Thanks for the two fixes in this PR! I've trimmed the branch so only the delete_everything_in_folder crash fix remains.

Why SUBPROCESS_ENCODING was removed

The intent — making the encoding configurable to handle Turkish (cp857) and similar non-UTF-8 Windows locales — is a good instinct, but the constant as written still hardcodes "UTF-8", so it doesn't actually fix the Turkish crash. More importantly, PR #298 (already merged) solved the root problem a different way: adding errors="backslashreplace" to both subprocess.run calls. This tells Python to escape any byte it can't decode as UTF-8 (e.g. \xNN) instead of raising a UnicodeDecodeError, so the program no longer crashes regardless of the system locale.

If a future improvement is wanted to decode the output correctly (rather than escaping bad bytes), the right approach would be to detect the system encoding at runtime:

import locale
encoding = locale.getpreferredencoding(False)  # returns e.g. "cp857" on Turkish Windows

That would be a separate PR on top of the current state.

What was kept

The delete_everything_in_folder crash fix in file_directory_functions.py is clean and still needed — os.listdir() raises FileNotFoundError if the folder doesn't exist, and no other merged PR covers this.
