General Tips

Backup the Original File: Before attempting any repairs, make a copy of the original partially downloaded file. Check File Size: Ensure the file size is not too small. A very small ZIP file is likely irrecoverable. Try Different Tools: If one tool fails, try another as different tools have varying levels of support for recovery.

Remember, if the ZIP file is significantly corrupted or incomplete, recovery might only be partially possible.
