Aquí está debajo de un script en Python para probar archivos zip ubicados en una o varias carpetas. Lo probé en Windows 7 SP1 x64 Ultimate pero esperaría que funcionara en cualquier sistema operativo.
Ejemplo de salida:
Total time spent was 577.64 seconds, checking 100 files, totaling 77.06 GB,
among which 0 were corrupted.

También escribe un archivo de registro que contiene todos los archivos zip válidos, así como un archivo de registro que contiene todos los archivos zip dañados.
