Add a Common Root Directory to ZIP Entries Using PathPrefix

See more Zip Examples

This example demonstrates how to use the PathPrefix property to prepend a common directory path to all entries added to a ZIP archive.

The PathPrefix value is prepended to the stored ZIP paths for subsequently added entries.

This is useful when:

• Creating ZIP archives that extract beneath a single root directory
• Packaging applications or projects into a named top-level folder
• Avoiding extraction directly into the current directory
• Organizing ZIP contents beneath a common parent directory

Suppose the local filesystem contains:

c:/MyProject/src/main.cpp
c:/MyProject/src/util.cpp
c:/MyProject/docs/readme.txt

And suppose the following code is executed:

zip.PathPrefix = "MyProject/";

Then the ZIP archive will contain:

MyProject/src/main.cpp
MyProject/src/util.cpp
MyProject/docs/readme.txt

Without a PathPrefix, the ZIP archive would instead contain:

src/main.cpp
src/util.cpp
docs/readme.txt

The PathPrefix is applied only to entries added after the property is set.
