Extract a Single ZIP Entry While Preserving Its Stored Path

See more Zip Examples

This example demonstrates how to use the ZipEntry.Extract method to extract a single entry from a ZIP archive.

The example first creates a ZIP archive containing a text file. It then re-opens the ZIP, finds the entry, and extracts it to a base directory.

The Extract method uses the relative path stored within the ZIP entry. Any required subdirectories are created automatically beneath the specified base directory.

success = False

# ------------------------------------------------------------
# First create a sample ZIP archive containing a small text file.

zip = chilkat2.Zip()

success = zip.NewZip("c:/temp/sampleText.zip")
if (success == False):
    print(zip.LastErrorText)
    sys.exit()

# Add a small text file from memory.
success = zip.AddString("myApp/docs/hello.txt","Hello from a ZIP entry!","utf-8")
if (success == False):
    print(zip.LastErrorText)
    sys.exit()

# Write the ZIP archive to disk and close it.
success = zip.WriteZipAndClose()
if (success == False):
    print(zip.LastErrorText)
    sys.exit()

# ------------------------------------------------------------
# Now open the ZIP archive we just created.

zip2 = chilkat2.Zip()

success = zip2.OpenZip("c:/temp/sampleText.zip")
if (success == False):
    print(zip2.LastErrorText)
    sys.exit()

# Find the entry by its stored ZIP path.
entry = chilkat2.ZipEntry()

success = zip2.EntryOf("myApp/docs/hello.txt",entry)

if (success == False):
    print("Entry not found.")
    sys.exit()

# Extract this single entry to the base directory:
# 
#     c:/temp/extracted
# 
# Because the entry's stored path is:
# 
#     myApp/docs/hello.txt
# 
# the file will be extracted to:
# 
#     qa_output/extracted/myApp/docs/hello.txt
# 
# The required subdirectories are created automatically.
success = entry.Extract("c:/temp/extracted")
if (success == False):
    print(entry.LastErrorText)
    sys.exit()

zip2.CloseZip()

print("Entry extracted successfully.")
