Utility for comparing the contents of 2 zip files

ZipDiff

Use the ZipDiff tool when you need to compare the contents of two zip files.

Run it as a standalone executable. The tool supports four output formats: plain text, HTML, JSON, XML and ZIP (containing differences).

This version of ZipDiff has been ported from Java to C# (.NET)

Download

To get a copy of ZipDiff you have the following options:

• Download the source and run the build.cmd (which runs an MSBuild against build.proj)
• Install using NuGet. Your options are:
  • ZipDiff - the command-line utility
  • ZipDiff.Core - the class-library (to use in your own applications)

Prerequisites

To use ZipDiff you will need to have the .NET Framework 4.0 installed.

Command line arguments

zipdiff.exe --file1 foo.zip --file2 bar.zip [--options]

Valid options are:

--comparecrcvalues            Compares the CRC values instead of the file content
--comparetimestamps           Compares timestamps instead of file content
--ignorecase                  Performs case-insensitive string comparison on the file name
--outputfile                  Name of the output file
--exitwitherrorondifference   Use an error code other than 0, if differences have been detected
--regex                       Regular expression to match files to exclude
--verbose                     Print detail messages

Output formats

When using the --outputfile option, the following formats are available:

• Plain-Text
• HTML
• JSON
• XML
• Zip (containing the differences between --file1 and --file2)

For example, to output a zip file:

zipdiff.exe --file1 foo.zip --file2 bar.zip --outputfile diff.zip

If the output file extension can not be determined, then the format will default to a plain-text file.
