Excerpt from the readme

What is this?

ZipDLL is a extension DLL for NSIS. It can unzip files from zip files. It is especially useful in combination with NSISdl so that you don't have to download large files uncompressed.

Using the header file

To use the dll, include "ZipDLL.nsh" after including the language files. To extract files from a zip file, use the following macro:

!insertmacro ZIPDLL_EXTRACT SOURCE DESTINATION FILE

Parameters

Zip file, destination directory, file to extract.

Description

Extract the specified file in the archive to the destination directory. If file is <ALL>, all files in the archive will be extracted.

On Success, the string "success" is on top of the stack, else an error message.

If using the macro, the status messages during extraction uses the current installer language. (Only if ZipDLL supports that language. Default language is English)

Example

!insertmacro ZIPDLL_EXTRACT "c:\test.zip" "c:\output" "<ALL>"
