CAZIPXP Compressed Archive

CAZIPXP Compressed Archive is a proprietary package format used by Broadcom's CA (formerly Computer Associates) software to deliver patches, diagnostic reports, and bundled utilities for Windows. It is created by Broadcom's CAZIPXP tool and serves as a self-contained archive of one or more files related to CA product maintenance or troubleshooting. These archives are commonly attached to cumulative update or rollup patch distributions, or generated by system diagnostic utilities to capture system state for support cases.

Creation of these archives happens during patch or diagnostic processes within CA products. These files are later uncompressed by the same utility, CAZIPXP, with a command-line instruction such as "cazipxp -u <archive_name>". Extracting reveals folders containing patch scripts, executables, log files, or other data needed to apply updates or debug issues.

The first five bytes of the file contain the ASCII string "CAZIP" starting at offset 0, serving as the format's signature. This distinguishes files of this format from unrelated uses of the same file extension.
