(Perl) Find a ZIP Entry by Exact Path Using EntryOf

See more Zip Examples

This example demonstrates how to use the EntryOf method to find a ZIP entry whose stored path exactly matches a specified path.

Unlike EntryMatching, which performs wildcard matching, EntryOf performs an exact path lookup.

This method is useful when:

• The exact ZIP path is already known
• Retrieving a specific file or directory entry
• Verifying whether a particular entry exists in the ZIP archive

Suppose the ZIP archive contains:

docs/
docs/readme.txt
docs/manual.pdf
images/logo.png
data/config/settings.json

ZIP archives may optionally contain explicit directory entries such as docs/. These directory entries can also be retrieved using EntryOf.

The example:

• Finds an exact file entry
• Finds an exact directory entry
• Demonstrates the difference between file and directory entries

Note: This example requires Chilkat v11.0.0 or greater.
