 - `ignoreAllWhiteSpaces` - boolean - ignore all white space differences (similar to `diff -w`)
 - `ignoreEmptyLines` - boolean - ignore differences caused by empty lines (similar to `diff -B`)
 - `respectGitIgnore` - boolean - include / exclude files based on .gitignore - this option works together with `includeFilter` and `excludeFilter` options. ⚠️ The extension supports the main basic gitignore rules. For instance, it supports negation (`!`), but it doesn't support .gitignore files in subfolders. If there is an important use case that is not supported, please open an issue.
+- `compareStrategy` - One of the options: "content", "size", "date"` - The strategy to use while comparing files. Comparing by `content`, `size` or `date` (last modified time). Default is `content`.
