Unzip 4gb file in C #

Question

I am using sharp lib for zip and unzip. It works great with a 4 GB file, so it is looking for some kind of .net framework solution. I tried Gzipcompression on dotnet. It also fails to unzip 4gb files. You know any other zip library that processes large files.

thank

Answer 1

DotNetZip will process ZIP64 archives (> 4.2 GB) correctly, in 100% managed code. This also (from my testing) has a significantly better feature set and does a better job than compression framework libraries (i.e., Equal or better performances with much smaller files - often around 1/3 the size of environment compression routines).

Answer 3

If the look is not a problem, you can use Shell FolderItems (shell32.dll), the only drawbacks are that it is a little difficult to use, and you get a Windows progress dialog, not a callback procedure.
