File Format
Name AS/ZC (Zip Chunker)
Ontology
Extension(s) .as, .zc
Released 1991

AS/ZC is what we're calling the container format used for file fragments, by the arbitrary-format mode of several file splitting utilities developed by Scott Jibben / Jibben Software. Specifically:

  • Zip Chunker (ZC), v2.00+
  • Archive Sizer, renamed to Zip Chunker Pro (ZCP) as of v3.00
  • LHA Chunker

The filename extension was changed from .AS to .ZC in ZC v3.01 and ZCP v3.01.

Note that the flagship feature of these utilities is splitting standard archive formats, in which case the AS/ZC format is not used.

Identification
