An MCR file may also be a macro created by JitBit Macro Recorder. It contains a list of plain text instructions that Macro Recorder reads to execute actions on a user's computer. To execute the actions an MCR file describes, open it in Macro Recorder and select Play .

A macro is a script used to automatically execute a complex or repetitive computer task. For example, a macro may contain instructions used to automatically open a word processing program and create a new, formatted document. Typically, each macro is assigned to a unique keyboard key combination (e.g. Control + K) used to execute it.

JitBit Macro Recorder allows you to create, edit, and execute macros. To create a new macro, press Macro Recorder's Record button and then perform the actions you want to include in their macro. You can also manually create and edit macros using the tools found in Macro Recorder's Insert menu.

After you finish creating a macro, you can save that macro as an MCR file. Each MCR file is a plain text file that describes the actions, screen coordinates, and time delay between actions used to execute a macro.

You can open an MCR file in JitBit Macro Recorder (Windows). To do so, select File → Open... from the program's menu bar and then open your MCR file.

You can also open an MCR file in Microsoft Notepad (Windows), Apple TextEdit (Mac), or any other text editor, to view the list of commands the MCR file contains.
