dt_Loc = loc1_ctab.GetEmpLocInfo(Session["empcd"].ToString());
string str = DateTime.Now.ToString("dd-mmm-yyyy");
str = dt_Loc.Rows[0]["loc1_abrv"].ToString() + "-" + str;

Your code giving such error because, the method Create Creates or overwrites a file in the specified path. which will return A FileStream that provides read/write access to the file specified in path. So at the time of executing the writemethod, the file is being used by the returned FS. you can use this in the following way:

using (FileStream fs = File.Create(path))
{
   Byte[] info = new UTF8Encoding(true).GetBytes(txt_comments.Text);
   // Add some information to the file.
   fs.Write(info, 0, info.Length);
}

You can Make it simple by using File.WriteAllText which will Creates a new file, write the contents to the file, and then closes the file. If the target file already exists, it is overwritten.

string path =FilesPath.Path_SaveFile + str + ".txt";;
if (!File.Exists(path))
{
    File.WriteAllText(path, txt_comments.Text);
}

Remove the File.Create since it opens a FileStream for the file.This results in the file being open and hence you get the exception that the file is being used by another process.

if (!File.Exists(path))
{            
     using(StreamWriter sw = new StreamWriter(path))
     {
         sw.WriteLine(txt_comments.Text);
     }
}
