Technical summary

yt-dlp sanitize_path can corrupt drive-relative paths by treating the drive marker like a normal separator.

Preserve Windows drive-relative prefixes while sanitizing the remaining path components.

The bug is specific to drive-relative path semantics, so the sanitizer must not collapse C:relative into an unrelated absolute path.

The snippet uses native project logic; the extractor filename is sanitized before yt-dlp joins it with the output directory. The helper result is consumed directly by the patched code path.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import yt_dlp; print('smoke test OK')"
