Dear Sir / Madam,

We need to check the AI file can able to open in CC 2019.

Is it posible to identify the AI file version(CS6,CC 2020..) using SDK?

If possible, please send the function name.

Thanks and Regards,

Here is a sample of detecter I wrote a few years ago.

Unfortunately, I don't have any snippets to use in such cases.
When handling character strings in C ++ The line feed code differs depending on the platform. If there is a difference between Windows and Mac, it is considered that there is a difference in behavior in this part. Reading in binary mode does not make this difference.
Also, if you just check the version, it will be easier to use JavaScript.

Thanks a lot for the quick reply.

I try to to read the file in binary mode. But it does not works.

Is it possible to provide sample code(how to check AI file version) in Javascript?

I have never tried a similar workflow. Why don't you read binary stream directory?
Search below code words and fetch the next 2 bytes are major versions.

The previous sample was made by Mac. There is no difference between Mac and Windows.
What version was the file created on the Mac?

Can you explore a header section start at "%!PS-Adobe-3.0"?

Thanks for the reply.

Yes. There is no difference between MAC and Windows.

But the file unable to read after 580th line and read the %%AI8_CreatorVersion code. I used the following code for read process.

Kindly guide us in this regards.

bool IsValidIllustratorFile(LPCTSTR pszPath)
{
	FILE *fRead;
	errno_t err = _tfopen_s(&fRead, pszPath, _T("r,ccs=UTF-8"));
	if (err != 0)
	{
		return 1;
	}
	CStdioFile file(fRead);
	CString strReadValue = _T("");
	CString strLinkedFile = _T("");
	bool bIsValidIllFile = true;
	int nCount = 0;
	try
	{
		while (file.ReadString(strReadValue))
		{
			++nCount;
			strReadValue.TrimLeft();
			CString strKey = _T("%%AI8_CreatorVersion");
			int nPos = strReadValue.Find(strKey);
			if (nPos != -1)
			{
				CString strTemp = strReadValue.Mid(nPos+ strKey.GetLength());
				if (strTemp.Find(_T("24")) != -1)
				{
					bIsValidIllFile = false;
					break;
				}
			}
		}
	}
	catch (...)
	{
		file.Close();
		return false;
	}
	file.Close();

	return bIsValidIllFile;
}

You can read the target files binary and search "%%AI8_CreatorVersion" key. Here is an example.

...
%!PS-Adobe-3.0 
%%Creator: Adobe Illustrator(R) 24.0
%%AI8_CreatorVersion: 24.1.0
%%For: (No41) ()
%%Title: (SAMPLE.ai)
%%CreationDate: 2020/04/07 14:28
%%Canvassize: 16383
%%BoundingBox: 209 -730
