The RESOURCES file extension is commonly associated with Visual Studio Resource Format files defined by Microsoft. RESOURCES files contain definitions for resources used in applications. They originate from programming languages like C, C++, and C#.
You can access RESOURCES files using the .NET Framework’s System.Resource namespace. The ResourceWriter class writes resources into RESOURCES files. RESOURCES files are similar to .RESX files. However, only resources within RESOURCES files should be embedded into a runtime executable.
The RESOURCES file extension can also be found in other file types. The format was developed by Microsoft most likely using the Microsoft Visual Studio program. To open these files, Microsoft Visual Studio application is recommended.
To make sure your RESOURCES file is not corrupted, get the file again and scan it. Also, update the application you use to open .RESOURCES files. Only the latest version supports the current format.
