- If Zip Comment
- Version 1.01

- Description
-
- If Zip Comment (IZC) is a simple utility. IZC detects the
- presence of a zip comment in a zipfile, and returns an errorlevel.
- It also gives information visually. It simply returns the following
- errorlevels:
-
- Errorlevel | Description
- ------------|--------------------------------------
- 0 | Error, or no file specified
- 1 | Zipfile contains a comment
- 2 | Zipfile does NOT contain a comment.
-
- If you forget which is which, simply typing IZC, with no
- parameters will produce a help screen telling you is which.
-
-
- Long Comments
-
- It should be noted that when comments reach a certain size,
- PKZIP/PKUNZIP will not be able to read them. When they get even
- larger, you will get an insufficient memory error. When there is
- an especially long comment in a file, and IZC is being used, your
- computer may seem to stop, with the drive access light coming on
- every 10 seconds or so. This is do to the fact that IZC searches
- for certain information, from the end of the file. This information
- is located immediately preceding the zip comment. IZC searches back
- in 2K blocks. If you have a 100k zip comment in a file, for
- example, IZC may take 8 minutes to process. So be wary of zip
- comments which are longer than a few kilobytes.
-
- Version #'s
-
- For compatibility purposes, IZC version numbers will follow
- that of PKZIP/PKUNZIP. Therefore, if you are using PKZIP .92, IZC
- .92 will definitely work. If you are using PKZIP 1.0, you should
- use IZC 1.0. However, this does not mean that IZC .92 will not
- work.
