What is an EFP file?

EFP files mostly belong to Joymax Engine.

Game Effect File: This EFP file type stores visual effects data used in game development. It contains information for particle animations, lighting, and other in‐game effects. Files of this kind are managed by proprietary game engines such as those provided by Joymax.
These files need specific modding tools or development software to view and modify the content.

Encrypted Form Package: Another use of the EFP extension is as an encrypted package for form data, often related to tax forms. Sometimes the internal format is labeled as CAP. Applications like FormTool and TaxAct handle these files to secure and process sensitive information. For more details about handling these, refer to FormTools.

EasyFit Distribution File: A further variation is the EasyFit distribution file. This type is designed for delivering pre-configured distribution data within the EasyFit environment.
It is tailored for deployment tasks using designated distribution software.

Check the file header to determine which usage applies.
Use the specialized software for the file’s intended purpose.
Be aware that different EFP files are not interchangeable across these use cases.

EFP file format details:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be deduced from the file extension and the signature. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Knowledge is power - this also applies when dealing with unknown or faulty files. Below you will find our evaluation of the EFP files:

EFP is not a common file extension and includes different formats for the applicable programs. The following file formats are most commonly found in EFP files:

50% of all EFP files are associated with SilkRoad effect. These are binary files, so they do not contain words or text. A typical file size is 16 KB. The following keywords are characteristic: NormalTimeLife, StaticEmit, LinkMode, Program, JMXVEFF 0011 and JMXVEFF 0013. Such EFP files store data about skill, system, avatar, motion, keep and 3D model.
15% of all EFP files are based on the popular CAP file format. CAP files are compressed archives. The first bytes (the signature) are 'MSCF' (short for MicroSoft Cabinet File). These files are binary files, so they do not contain text, but only cryptic characters. Most of these files are 53 KB to 770 KB in size. The following keywords are characteristic: Form, MSCF and FormPak. These files can be linked to form.
