Overview

What is a RESX file? A RESX file is a resource file used by a program developed using Microsoft's .NET Framework. It contains objects and strings that the program uses, placed within XML tags. RESX files can contain both plain text and binary data. Binary data is encoded as text.

More Information Developers commonly store application settings and program resources, such as pictures, in RESX files. If implemented correctly, this allows a developer to modify or update a program's resources without recompiling it, by swapping one RESX file for another. This can be useful when, for example, localizing programs for different regions and languages. If a RESX file contains binary data encoded as text, that text is saved within <data> </data> tags. Examples of binary data that a RESX file might contain include program properties and MIME types.
