Im running my program from visual studio 2012 pro as admin. I ran the visual studio as admin.

For example now the exception error is on the line:

Directory.CreateDirectory(outputtext);

UnauthorizedAccessException Access to the path 'C:\Users\bout0_000\AppData\Local\OutputFiles\outputtext' is denied.

And also windows it self throw me a window in the middle of screen say: Location is not available and then inside i see description to check network to check if disk i inserted....etc.

If im running my program as admin why i dont have access ?
Is there any directories maybe i can use that have access to any users when its under admin rights ? Or maybe without admin rights ? Instead this:

C:\Users\bout0_000\AppData\Local\OutputFiles\outputtext

Maybe there is some other location at C:\Users\bout0_000\AppData\Local that is not need admin at all ? Maybe C:\Users\bout0_000\AppData\Local\Temp ?

This is the complete exception error:

System.UnauthorizedAccessException was unhandled
  HResult=-2147024891
  Message=Access to the path 'C:\Users\bout0_000\AppData\Local\OutputFiles\outputtext' is denied.

There are some things wrong in your code, give this modified version a try:

public static void CreateDirectories()
    {

        outputfiles = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "OutputFiles");
        if (Directory.Exists(outputfiles)) Directory.Delete(outputfiles, true);            
        outputtext = outputfiles + "\\outputtext";            
        Directory.CreateDirectory(outputtext);

        outputphotos = outputfiles + "\\outputphotos";
        Directory.CreateDirectory(outputphotos);

        temptxt = outputfiles + "\\txtfiles";
        Directory.CreateDirectory(temptxt);

        tempphotos = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + "\\photosfiles";
        if (Directory.Exists(tempphotos)) Directory.Delete(tempphotos, true);
        Directory.CreateDirectory(tempphotos);            

        photofilesDir = outputphotos + "\\" + "photosfiles";            
        Directory.CreateDirectory(photofilesDir);

        photofilesDir1 = outputphotos + "\\" + "photosfiles1";
        Directory.CreateDirectory(photofilesDir1);

        photofilesDir2 = outputphotos + "\\" + "photosfiles2";
        Directory.CreateDirectory(photofilesDir2);

        photofilesDir3 = outputphotos + "\\" + "photosfiles3";
        Directory.CreateDirectory(photofilesDir3);
    }

Some notes:

It looks like that you want to delete the old outputfiles folder before creating a new one. Deleting with Directory.Delete(path,true) will delete all the subdirectories and files. So all the sub-folders (outputphotos, outputtext,...) obviously don't exist after you delete the outputfiles folder and create a new one. That means, we don't have to check if the sub-folders exist or not, just create new ones. The same logic is also applied to outputphotos folder.
You don't have to create parent directory first before creating the sub directory. Directory.CreateDirectory(path) will create all the parent directories needed before creating the sub-directory (the last in the path).

Why am I getting this error sometimes : Location Is Not Available?
