  • This is good place to ask questions about reverse engineering. The more detail you provide about the problem you are having the more likely it is someone will be able to help you. A list of resources for beginners can be found here. Can you provide more specific info in your question about the file and steps you have taken to analyze it? – julian Mar 15 '17 at 3:12

We call it data (file format) reverse engineering but, it is also bounded with software reverse engineering because you need to examine (if you have) actual software which creates, edits, extracts this file-type. Reverse Engineering Stack Exchange is not a forum but, it is most helpful community i have ever seen. Also, just a few active forums discuss reverse engineering topics and they expect you know some basics about this field. Most people don't want to help step to step reverse engineering to somebody. For resources i can recommend you Reversing: Secrets of Reverse Engineering to start. It discuss theoretical basics and practical examples of reverse engineering including your needs.
