Does moving a CAT-file-signed executable to a different location invalidate its digital signature?

No, moving the file does not invalidate the CAT digital signature. The article demonstrates that after relocating xwizard.exe, both `signtool.exe verify /pa /a` and `sigcheck.exe` still report the signature as valid. This is because the signature is stored in the system catalog database, not tied to the file path. This behavior is important for understanding file trust mechanisms in Windows.
