Add Multiple Files to a ZIP Using AppendFiles

See more Zip Examples

This example demonstrates how to use the AppendFiles method to add multiple files matching wildcard patterns to a ZIP archive.

The example adds:

• All .txt files from one directory.
• All .xml files recursively from another directory tree.

The AppendFiles method adds references to matching files in the local filesystem. The files are not actually read or compressed until a Write* method is called.

When recursive mode is enabled (recurse = _TRUE_), relative subdirectory paths are preserved within the ZIP archive.

For example, suppose the local filesystem contains the following directory tree:

c:/data/invoices/2024/january/inv001.xml
c:/data/invoices/2024/january/inv002.xml
c:/data/invoices/2024/february/inv003.xml

And the following call is made:

zip.AppendFiles("c:/data/*.xml",_TRUE_);

Then the following paths will be stored in the ZIP archive:

invoices/2024/january/inv001.xml
invoices/2024/january/inv002.xml
invoices/2024/february/inv003.xml

The portion of the path preceding the wildcard root (c:/data/) is not stored in the ZIP archive.
