	11	+	## Description
	12	+
	13	+	`OpenDocument` opens a document/file with the default viewer/editor registered with the operating system for that file/file extension.
	14	+
	15	+	- On macOS, the code calls the [[macOS Open Sesame\|open]] command line utility for files and directories. This will open the default application for the file or directory as determined by LaunchServices.
	16	+	- On Windows, the code will use the registry to look up the file association for the extension. As with macOS, it will also open directories.
	17	+
	18	+	On both macOS and Windows, `OpenDocument` will also open a URL using the default web browser.

	20	+	## Example
	21	+
	22	+	``` pascal
	23	+	uses
	24	+	LCLIntf;
	25	+	begin
	26	+	OpenDocument('readme.pdf');
	27	+	```
