<p><b>New page</b></p><div>{{FormatInfo<br />

'''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:<br />
<br />
* '''Zip Chunker''' (ZC), v2.00+<br />
* '''Archive Sizer''', renamed to '''Zip Chunker Pro''' (ZCP) as of v3.00<br />
* '''LHA Chunker'''<br />
<br />
The filename extension was changed from '''.AS''' to '''.ZC''' in ZC v3.01 and ZCP v3.01.<br />
<br />
Note that the flagship feature of these utilities is splitting standard archive formats, in which case the AS/ZC format is not used.<br />
<br />
== Identification ==<br />
AS/ZC files are observed to start with ASCII "{{magic|AS}}", followed by bytes {{magic|af 10 64 00}}, though it's unclear how much of this can be relied on as a signature.<br />
<br />
== Software ==<br />
''For DOS, except as noted.''<br />
