.M11 File

The m11 file extension is associated with Microsoft Money, a personal finance management software, developed by Microsoft Corporation.

The .mn1 to .m16 files are created after installation of a Microsoft Money new version. It is a part of the conversion process, it creates a backup copy of your unconverted file.

The file uses the relevant extension to the version it was last used in. These files are not required for Money to run, but you should be sure you will never revert to an older version of Money again before you delete them.

These files can be opened in the previous version of Money, not the mny file.

As of 2010, the product is officially discontinued and no longer supported by Microsoft.

This m11 file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
