Unable to Copy files from one directory to another.

Question

I'm using the following code to copy a folder and the subfolders within to another location:

     using UnityEngine;
     using UnityEngine.UI;
     using System.IO;

     public class MainScript : MonoBehaviour {
     
     public void Save () {
             modFolder = System.Environment.GetFolderPath (System.Environment.SpecialFolder.MyDocuments) + "/Mods";
             modFolder = modFolder.Replace(@"/", @"\");   
             string dataL = "/Data";
             dataL = dataL.Replace(@"/", @"\");
     
             string path1 = directory + dataL;
             string path2 = Application.streamingAssetsPath + dataL;
     
             string[] directories = Directory.GetDirectories (modFolder + dataL);
             string[] files = Directory.GetFiles(modFolder + dataL);
     
             foreach (string folder in directories) {
                 string[] subfiles = System.IO.Directory.GetFiles(folder);
                 if (!Directory.Exists(folder))
                 {
                     Directory.CreateDirectory(folder);
                 }
                 foreach (string subfile in subfiles) {
                     string fileName = Path.GetFileName (subfile);
                     string destFile = @"\" + fileName;
                     string destFile2 = @"\" + fileName;
                     File.Copy (subfile, destFile, true);
                     File.Copy (subfile, destFile2, true);
                 }
             }
     
             foreach (string s in files) {
                 string fileName = Path.GetFileName (s);
                 string destFile = Path.Combine (path1, fileName);
                 string destFile2 = Path.Combine (path2, fileName);
                 if (!Directory.Exists(path1))
                 {
                     Directory.CreateDirectory(path1);
                 }
                 if (!Directory.Exists(path2))
                 {
                     Directory.CreateDirectory(path2);
                 }
     
                 File.Copy(s, destFile, true);
                 File.Copy(s, destFile2, true);
     
             }
         }
     }

The problem is that when I press the save button, Unity gives me the error: UnauthorizedAccessExeption: Access to path "C:\Users\Mike\Documents\Mods\Data\Test\Test.txt" or "\Test.txt" is denied. System.IO.File.Copy (System.String sourceFileName, System.String destFileName, Boolean overwrite) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/File.cs:124)

Have you tried launching Unity in administrator mode? If not try building your project and launching it on administrator mode.

It didn't work but I went back and tried rewriting my code it and got it to work. Here's my code:

     public void Save () {
         modFolder = System.Environment.GetFolderPath (System.Environment.SpecialFolder.MyDocuments) + "/Mods";
         modFolder = modFolder.Replace(@"/", @"\");   // explorer doesn't like front slashes//
 
         string [] files = Directory.GetFiles ( modFolder + @"\Data", "*.*", SearchOption.AllDirectories);
         string tDirectory = directory + @"\Data";
         tDirectory = tDirectory.Replace(@"/", @"\");
         string sDirectory = modFolder + @"\Data";
 
 
 
         for (int x = 0; x < files.Length; x++) {
             string destination = tDirectory + files[x].Substring (sDirectory.Length);
             if (!Directory.Exists (Path.GetDirectoryName(destination))) {
                 Directory.CreateDirectory(Path.GetDirectoryName(destination));
             }
             File.Copy (files[x], destination, true);
         }
     }
