What is an FMX file?
An .FMX file is a compiled software file. It has several possible meanings. The most common use is a Compiled Oracle Forms Module. Developers use Oracle Forms to build enterprise database applications. When they compile the source code, it creates an .FMX file. This file runs in the Oracle Forms runtime environment.
Another common use is an FME Custom Transformer file created by Safe Software FME. It can also be a FileMaker Plug-in used to add features to FileMaker databases.
How to open FMX files?
You need the correct software to open an .FMX file. For Oracle files, you need the Oracle Forms runtime. For FME files, you need FME Form. For a FileMaker Plug-in, you must install it inside FileMaker.
Since these files are usually compiled binaries, they are difficult to read with a standard text editor. You cannot edit them directly. Instead, you must edit the original source file and compile it again.
