(PureBasic) Create Empty File and Directory Entries in a ZIP

See more Zip Examples

This example demonstrates how to use the AddEmpty method to create both empty directory entries and empty file entries within a ZIP archive.

The example creates:

• A truly empty directory named emptyDir
• An empty file named empty.txt located beneath the docs subdirectory

When the ZIP archive is extracted:

• emptyDir will be created as an empty directory.
• docs/empty.txt will be created as an empty file under the docs subdirectory.

It is not necessary to explicitly create the docs directory beforehand. The directory structure implied by the file path is created automatically when extracting.
