Files that contain the .resx file extension are most commonly associated with the Microsoft .NET Framework. These files contain resource files that are used by applications that have been developed using the Microsoft.NET framework.
The RESX files that are created with this framework contain strings and objects for an associated program, saving the information in the XML file format. The RESX file may contain binary or plain text data, which is then encoded with the proper XML tags.
RESX files are frequently used to store program settings and application resources.
The Payroll Mate software application has also been reported to use the .resx file suffix. These RESX files contain data files that are referenced by the Payroll Mate application.
