Determining binary/text file in labview?( without extension )

[imadouino]

Hi,

How can i determine if the file and binary o a text by looking at the content and without checking the extensions?

I find this solution but i dont know how i an do it in labview.

 Please help me if you have other method easier.

-Read first 2K bytes (or less if file is not enough big)
-If a file contains only the decimal bytes 9–13, 32–126, it's probably a pure ASCII text file
-If, in addition to the above bytes, the file contains only the decimal bytes 128–255, it's probably a text file in an 8-bit or variable-length ASCII-based encoding such as ISO-8859-1, UTF-8 or ASCII+Big5.
-If not, for some purposes you may be able to stop here and consider the file to be binary
 
-If a file doesn't meet the above constraints, examine the first 2–4 bytes of the file for a byte-order mark => UNICODE (UTF-8, UTF-16 or a text file encoded in the current code page of the host operating system)
  EF BB BF     UTF-8
  FF FE        UTF-16, little endian
  FE FF        UTF-16, big endian
  FF FE 00 00  UTF-32, little endian
  00 00 FE FF  UTF-32, big-endian

Thank you ,

I answered this question for you on 15 May 2017, and you already accepted it as a solution.  So why are you asking it again, and proving an answer that you are rejecting?  Why don't you follow the answer that you already accepted?

I'm sorry, but it's not the same question ,in any case thank you I found the solution

It sure sounds exactly the same.

The short answer is you can't because there really is no difference between a binary file and a text file except for how a human uses the data within.  Therefore, you will have to determine an algorithm that resembles what would qualify as a text file for a human being.
