If you are developing this feature within an application, follow this general logic: : Identify if a file ends in .001 .
To support files like li14f.7z.001 , your feature should include:
: The system must automatically scan the local directory for subsequent parts (e.g., .7z.002 , .7z.003 ).
: Use the 7-Zip SDK or LZMA SDK to handle the underlying decompression.
: Before extraction, verify that the combined file size matches the expected total or check for a missing "tail" part to prevent "Unexpected end of data" errors.
