Once the file is downloaded, the feature must verify that it hasn't been corrupted.

Because the target is a .rar file, your environment will need a library capable of handling the format (which is proprietary). Once the file is downloaded, the feature must
: Compare the downloaded file's SHA-256 or MD5 hash against a known manifest. Verify file_hash = hashlib
: Parse the filename bits ( 1307072M and 47E78S ). These often correspond to: Part Number : 1307072M Revision/Region Code : 47E78S 4. Implementation Example (Python Logic)
