: The system must automatically scan the local directory for subsequent parts (e.g., .7z.002 , .7z.003 ).

To support files like li14f.7z.001 , your feature should include:

: Alert the user if any numbered parts in the sequence are missing.

: Often caused by a corrupted segment or a virus; include a "file repair" or "re-download" prompt.

: If only the .001 file exists, the archive is incomplete and cannot be opened.

: Call the extraction method on the .001 file, which naturally acts as the entry point for the entire archive. Troubleshooting Common Errors

You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip.

: Users should only need to select the .001 file; the feature must programmatically "join" and extract all subsequent parts as a single stream. Implementation Workflow
