Can you identify file type without extension

We may come across this situation when we get a file with out extension or given incorrectly. But, we have options in some operating system that will search and match the program associated with the unknown file type.

I had situation recently, a file with incorrect extension. I was trying to open the file in text edition (binary mode) to identify the file type manually. But, I could not do it simple reading the file content.

Finally found a tool that does what i was trying to do manually. This is light weight tool with easy to update external data dictionary for file finger print matching data.
