I changed now thw button2 click event using StreamReader so it will ReadToEnd(); each text file in the split directory.

But it doesn't work it doesn't readl to end the files.

Im getting error on the line: r = new StreamReader(fi[i].ToString());

The error say: FileNotFoundException: Could not find file 'D:\C-Sharp\Google_Translate\Google_Translate\Google_Translate\bin\Debug\File0000.txt'.

And the text files are in d:\testsplit

Cant figure out why its trying to read the files from the C-Sharp...directory instead from d:\testsplit

Here is the code again with the changed fragment:

        if (result1 == DialogResult.OK)
        {
            SplitFiles(file1, 1024 * 32, splitDirectory);
            dir1 = new DirectoryInfo(splitDirectory);
            fi = dir1.GetFiles("*.txt");
            StreamReader r;
            for (int i = 0; i < fi.Length; i++)
            {
                r = new StreamReader(fi[i].ToString());
                string y = r.ReadToEnd();
                t.SourceLanguage = comboBox1.Text;
                t.TargetLanguage = comboBox2.Text;
                t.SourceText = y;
                t.Translate();
            }
            CombineFiles(@"d:\testsplit\newFileTranslated.txt", splitDirectory); // to change string newlargeFile to a new file name or the same file the user will select if the same name change file name and which directory to
            // save the file to using the current format sample in the CombineFile function \\
            // to check why its not translating the small files inside the for loop before combining them \\ 
            button1.Enabled = true;
        }

I suppose you need to

• change the working directory to the directory that contains the files

  Environment.CurrentDirectory = @"d:\testsplit";
  

• or prepend the path to the filenames (make them absolute @"d:\testsplit\test.txt")
