What is a .MMU file?
The .MMU file extension is associated with a type of file known as a myPM Merge Data File. This file is specifically created by a software application called myPM Merge. The primary function of this application was to facilitate the creation of merged documents that could be used in Microsoft Word and Excel. The content of a .MMU file includes what is known as a merge definition. This merge definition plays a crucial role as it outlines several important aspects: 1. **Input File**: It specifies the source file which contains the data needed for the merge. This file is typically in Microsoft Access or Excel format. 2. **Merge Settings**: These settings determine how the data from the input file will be arranged and transferred into the output file. This includes mapping specific data fields and possibly applying custom filters to refine which data is included. 3. **Output File**: It defines the destination file where the merged results will be saved, which can be either a Microsoft Excel spreadsheet or a Word document.
To use .MMU files, the myPM Merge software must be installed on your computer. This software relies on having Microsoft Access, Excel, and Word installed as it integrates with these applications to manage data and produce the merged documents.
However, it's important to note that myPM Merge has been discontinued and is no longer available for new downloads. This means that if you do not already have the software installed, obtaining it might be challenging.
For those who have the software, .MMU files can be opened using Midori Media's myPM Merge program. Since the software is discontinued, users should ensure they maintain their existing installation and be cautious with system upgrades that might affect the software's functionality.
