Test your knowledge: high-level file operations

Review

1. Which statement accurately describes shutil.copy2()?

   copy2() uses copystat() to preserve metadata where supported, but no copy API can promise all platform-specific metadata.
2. How do you skip names matching *.tmp while recursively copying a directory tree?

   copytree() accepts an ignore callable; ignore_patterns() creates the callable from shell-style name patterns.
3. What may shutil.move() do if a simple rename cannot move a path across filesystems?

   shutil.move() can fall back to copying and then removing the source; this is not necessarily an atomic move.
4. What is the most important rule when using shutil.rmtree()?

   rmtree() recursively deletes entries. Its symlink-attack resistance also depends on platform capabilities.
5. What units does shutil.disk_usage() use for total, used, and free?

   disk_usage() returns a named tuple of total, used, and free space measured in bytes.
6. When extracting an ordinary tar archive using unpack_archive(), which guidance is correct?

   The data filter mitigates several dangerous tar features, but it does not remove every risk; ZIP extraction does not accept the filter argument.
