ZIPDS - Zipfile Date Stamper
v1.1a, 03-04-89
Copyright 1989 Samuel H. Smith


This utility can be used to QUICKLY update the date/time stamp on a
bunch of Zipfiles. It also checks for truncated or garbled ZIPs (it
does not verify the CRC, but still catches about 80% of all bad
Zipfiles.)

It will update my entire upload directory in less than a minute. When
used with 'sweep' (or similar) it can be used to globally update all
Zipfiles on your system.


Usage: zipds *.ZIP [>OUT]

Sets non-0 errorlevel on truncated or corrupt Zipfiles


Example:
zipds d:\upload\*
if errorlevel 1 goto errors


I write ZIPDS because PKZIP 0.90 cannot update zipfile timestamps
without also updating at least one member file, making it impractical to
use for batch updates.

Revision History
----------------

02-19-89 v1.0
Initial release

03-03-89 v1.1
Added error messages compatible with ProDoor for faulty zipfiles.
This is required when testing zipfiles under prodoor 2.8 and 2.9 due
to the inconsistancy of error messages generated by 'PKUNZIP -t'.

03-04-89 v1.1a
Slight change in output format to prevent ProDoor from displaying the
directory in which the file resides. Changed date-stamp logic to
prevent removing date entirely on corrupt zipfiles.
