Not: Implemented 7zip

// Load 7z.dll dynamically HMODULE h7zLib = LoadLibrary("7z.dll"); if (!h7zLib) printf("Failed to load 7z.dll"); return;

This error isn't necessarily a bug; it is a limitation of the current version or the specific file type being handled: not implemented 7zip

Sometimes the "Not Implemented" error occurs specifically during a drag-and-drop operation from the 7-Zip GUI to a folder. Select the file inside 7-Zip, click the // Load 7z

: If you're using the command line, avoid the *.* wildcard. 7-Zip handles wildcards differently than Windows; use * or omit it entirely to avoid processing errors. if (!h7zLib) printf("Failed to load 7z.dll")

Occasional probelm when editing content in .bup file with 7 zip
