Ejemplo de ficheros multiparte en formato Zip:

fichero.z01
fichero.z02
fichero.z03
fichero.zip

Típico error al intentar descomprimirlo de la forma tradicional.

zipfile claims to be last disk of a multi-part archive;
 attempting to process anyway, assuming all parts have been concatenated
 together in order.  Expect "errors" and warnings...true multi-part support
 doesn't exist yet (coming soon).

cat fichero.* > fichero_completo.zip
zip -F fichero_completo.zip
unzip fichero_completo.zip

zip -F fichero.zip --out fichero_completo.zip
mkdir Directorio && cd Directorio
unzip fichero_completo.zip
