This commit (and PR) introduces a **new function** to retrieve free disk space in a unified manner across macOS, Linux, and Windows.
It refactors existing logic to ensure consistency, readability, and maintainability.
- **Common**
- Introduced a new function/method to retrieve free disk size in a consistent manner across platforms.
- **macOS**
- Implemented a mount-based approach using `statfs()` to fetch free space.
- Physical or container disks (like `disk0` or APFS containers) may return **-1** if they have **no** mounted filesystem.
For example, APFS containers are not directly mounted but contain APFS volumes; only the volumes have valid mount points.
- **Linux**
- Leveraged existing logic with `statvfs()` for retrieving free space.
- Minor refactoring.
- **Windows**
- Maintained the `GetLogicalDriveStrings()` + `GetDiskFreeSpaceEx()` approach for free size.
- Returning **-1** indicates an **unreachable** or **unmounted** filesystem. This behavior is most commonly seen on **macOS** with APFS containers or physical devices that are **not** directly mounted.
- In all scenarios, if the disk cannot be located or if the OS functions fail, **-1** is returned to signify no valid free-space calculation.

Thanks for this, I just started using this lib and wished it had the disk free space too. Not to be greedy but it would be nice to have the mountpoint/drive letter available too. |
