(Chilkat2-Python) Control Stored ZIP Paths Using AppendFromDir

See more Zip Examples

This example demonstrates how to use the AppendFromDir property to control which portion of a local filesystem path is stored within a ZIP archive.

When files are added using methods such as AppendFiles, AppendFilesEx, or AddFile, the stored ZIP path is determined relative to the AppendFromDir directory.

This property is especially useful when:

• Creating ZIP archives with clean relative paths
• Excluding unwanted leading directory portions from ZIP entries
• Packaging projects or directory trees while preserving selected relative path information

Suppose the local filesystem contains:

c:/abc/123/myAppDir/readme.txt
c:/abc/123/myAppDir/config/settings.json
c:/abc/123/myAppDir/images/logo.png

And suppose:

zip.AppendFromDir = "c:/abc/123";

Then the following call:

zip.AppendFiles("c:/abc/123/myAppDir/*",True);

Will store these paths in the ZIP archive:

myAppDir/readme.txt
myAppDir/config/settings.json
myAppDir/images/logo.png

Without AppendFromDir, the ZIP archive paths would instead begin relative to the append root:

readme.txt
config/settings.json
images/logo.png

The AppendFromDir property affects subsequently added filesystem entries.
