# Summary:

After downloading a ZIP archive, the fastest and simplest way to expand it is to just double-click the file, which opens the Archive Utility application.

However, if the archive contains entries marked as made under MS-DOS (e.g. any ZIP archive generated by the git-archive utility), the execute bit is added to the expanded files.

This is very frustrating when the expanded file is a text file without a filename extension (e.g. LICENSE, README):
- The file is treated by macOS as an executable. Double-clicking it will open the Terminal instead of a text editor.
- If the archive was downloaded from the Internet (e.g. github.com), the file is also marked as quarantined.

This is also inconsistent with the behavior of the unzip command.

# Steps to Reproduce:

1. Open the Terminal.
2. Execute the following command:

    echo Hello World > README && zip -k Archive.zip README && rm README && open -a Finder .

3. A Finder window opens. Double-click the ZIP file in that window.
4. Archive Utility expands a "README" file in the current folder. Double-click that "README" file.

# Expected Results:

The "README" file should open in the TextEdit application.

# Actual Results:

A new Terminal window opens and tries to execute the "README" file.

# Version/Build:

macOS 10.13.3 (17D47)
Archive Utility 10.10 (81)
