MAU files are used in Windows operating systems. The MAU file extension stands for Media Attachment Unit. These files fall under the Misc Files category along with 6033 other file extensions.
The recommended software for opening MAU files is Open or Run itself. MAU files can be opened on all system platforms, but support varies.
To open a MAU file on Windows, right-click on the file then click “Open with”>”Choose another app”. Select the desired program and check “Always use this app to open .MAU files”. On Mac, right-click the MAU file, click “Open with”>”Other…” and select the program.
While over 6030 file types use the .MAU extension, most are likely incompatible. Different programs may use the MAU extension for different data types. We receive suggestions on which programs users find useful for opening these files.
There are also free online MAU file tools and apps to view, edit, convert, merge, split, and compare MAU files without installing anything. However, the MAU file type seems to be obsolete now. In the past it was likely used for some type of attachment.
