[Ann] Identify Your InDesign File

I made some modifications, so now it seems to show correct CC version, like CC 2015 or CC 2017 + some minor code formatting

//DESCRIPTION:Test InDesign file for version
// A Jongware Script 27-Jun-2013
/*
    Modified 30 March 2017 
        By: Oleh Melnyk 
        Reason: to show actual CC version, for example "CC 2014" or "CC 2017" instead of "CC.next" or "CC.next.next.next"; + some general code formatting

Lines 57-62 responds for showing correct CC version

I really need help. I am using the newest version of Indesign and I saved it as Idml but it won't open. It says it may not support it or there may be a missing plugin. Tried from another computer but it still won't open.

Jongware, I don't understand how to use your "identify" file to find out information about my InDesign file. How do I do this?

Thank you.

Jongware this is cool, but wondering if you could update it to show CC, CC 2014, and CC 2015?  (It reports things like "CC.next.next" and "CC.2" instead.)

thanks!

Thanks Jongware. That was super helpful!

Here is how to do the same kind of thing in C#:

using System;
using System.Linq;
using System.IO;
namespace InDesignWrapper {
  class VersionChecker {
    private byte[] InDesignFileHeader = new byte[] { 0x06, 0x06, 0xED, 0xF5, 0xD8, 0x1D, 0x46, 0xe5, 0xBD, 0x31, 0xEF, 0xE7, 0xFE, 0x74, 0xB7, 0x1D };
    private int byteOrderFlag;
    public string GetInddFileVersion(string filename) {
      var fileinfo = new FileInfo(filename);
      var stream = fileinfo.OpenRead();
      var reader = new BinaryReader(stream);
      var fileHeader = reader.ReadBytes(16);
      if (!fileHeader.SequenceEqual(InDesignFileHeader))
        return "Not an InDesign file";
      string fileType = new String(reader.ReadChars(8));
      byteOrderFlag = reader.ReadByte();
      reader.ReadBytes(4);
      var majorVersion = reader.ReadInt32(byteOrderFlag) - 2;
      var minorVersion = reader.ReadInt32(byteOrderFlag);
      return String.Format("CS {0}.{1}", majorVersion, minorVersion);
    }
  }
  static class BinaryReaderExtensionMethods {
    public static byte[] ReadOrderedBytes(this BinaryReader reader, int count, int byteOrderFlag) {
      if (byteOrderFlag == 2) return reader.ReadBytes(count).Reverse().ToArray();
      return reader.ReadBytes(count);
    }
    public static long ReadInt32(this BinaryReader reader, int byteOrderFlag) {      
      return BitConverter.ToInt32(reader.ReadOrderedBytes(4, byteOrderFlag), 0);
    }
  }
}

So I can open a CS5.5—with Soxy— and it will then script it and save as CS5.5 rather than auto open the IDD as CS 6? More clarification please.

sorry where can i locate the User scripts folder in 10.6.8?

and how should i launch the script?

sorry, i am script newbie!

thanks

I tested this in CS3 and it appears to work. Magic!

Aw. c'mon. What fun is that? <big wink>

Thanks Jongware - that looks good. Not sure what I'll use it for.

Where did the need for this come from though?
