Exclude Multiple Directories When Adding Files to a ZIP

See more Zip Examples

This example demonstrates how to use the ExcludeDir method to exclude specific directory names when recursively adding files to a ZIP archive.

The ExcludeDir method excludes directories by name. Any directory matching an excluded name is skipped entirely, including all files and subdirectories beneath it.

This is useful for excluding directories such as:

• .git
• node_modules
• bin
• obj
• Temporary or cache directories

Call ExcludeDir once for each directory name to exclude.

Suppose the local filesystem contains:

c:/project/src/main.cpp
c:/project/src/util.cpp
c:/project/bin/app.exe
c:/project/obj/main.obj
c:/project/.git/config
c:/project/node_modules/library/index.js

After excluding bin, obj, .git, and node_modules, only the files beneath src are added to the ZIP archive.

The resulting ZIP archive contains:

project/src/main.cpp
project/src/util.cpp

Lua

local chilkat = require("chilkat")

local zip = chilkat.Zip.new()

local success = zip:new_zip("project.zip")
if not success then
    print(zip.last_error_text)
    return
end

-- Exclude several directory names.
--
-- Any directory matching one of these names will be skipped
-- during recursive file appending.
zip:exclude_dir("bin")
zip:exclude_dir("obj")
zip:exclude_dir(".git")
zip:exclude_dir("node_modules")

-- Recursively append all files beneath c:/project.
--
-- Because saveExtraPath = true, the ZIP paths will
-- include "project/" as the leading directory.
local recurse = true
local saveExtraPath = true
local archiveOnly = false
local includeHidden = true
local includeSystem = false

success = zip:append_files_ex("c:/project", recurse, saveExtraPath, archiveOnly, includeHidden, includeSystem)
if not success then
    print(zip.last_error_text)
    return
end

-- Write the ZIP archive.
success = zip:write_zip_and_close()
if not success then
    print(zip.last_error_text)
    return
end

print("ZIP archive created successfully.")
