how can import data from a file which has no extension

The file has some useful data but i am unable to open it....file has been attached bellow need your help to open it

[Jan]

You should have any further information about the file. Where did you get the file from? What kind of data are you expect? How do you know the the file contains "some useful data"? Having the file only, which is partially a text and partially a binary file, does not allow to guess its format.

Looks like a binary format that is not a mat file. For V5 Matfile the first 116 bytes should be readable ascii, for v4 start with a MOPT header. Neither can be found. So without answering Jan's questions we can't help you.

@SANKAR JYOTI NATH: you have three options:

1. Find an existing file parser for that file specification (e.g. researchers, FEX, etc).
2. Write it yourself using that specification (hint: fread, fscanf, etc).
3. Get someone else to write it for you (paying a few pieces of eight of course).
