    So I googled for a second and found:
    For Each foundFile As String In My.Computer.FileSystem.GetFiles( _
        My.Computer.FileSystem.SpecialDirectories.MyDocuments, _
        FileIO.SearchOption.SearchAllSubDirectories, "*")
     
        My.Computer.FileSystem.DeleteFile(foundFile)
     
    Next
    Code (markup):
    This code will search your MyDocuments folder and all its sub-folders for all files and delete them.
    "*" is the pattern for ALL, you can use "*.txt" to file text files only or just "haha*" to delete any file that its name starts with "haha", no matter how it continues.

    You could always try and mess with the folder permissions.

    Dim FolderPath As String = "C:\test\myfolder"
     
    Dim UserAccount As String = "domain1\testuser"
     
    Dim FolderInfo As IO.DirectoryInfo = New IO.DirectoryInfo(FolderPath)
     
    Dim FolderAcl As New DirectorySecurity
     
    FolderAcl = FolderInfo.GetAccessControl()
     
    FolderAcl.AddAccessRule(New FileSystemAccessRule(UserAccount, FileSystemRights.FullControl, InheritanceFlags.ContainerInherit Or InheritanceFlags.ObjectInherit, PropagationFlags.None, AccessControlType.Allow))
     
    FolderInfo.SetAccessControl(FolderAcl)
    Code (markup):
    Or change your test user for the app.

    File permissions can be a headache.

    Just go to Project Settings -> Application Tab and click on the "View UAC Settings" or "View windows settngs" button.

    In the new tab opened, you will see a code like this,


    <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
            <!-- UAC Manifest Options
                If you want to change the Windows User Account Control level replace the
                requestedExecutionLevel node with one of the following.
    
            <requestedExecutionLevel  level="asInvoker" uiAccess="false" />
            <requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />
            <requestedExecutionLevel  level="highestAvailable" uiAccess="false" />
    
                Specifying requestedExecutionLevel node will disable file and registry virtualization.
                If you want to utilize File and Registry Virtualization for backward
                compatibility then delete the requestedExecutionLevel node.
            -->
            <requestedExecutionLevel level="highestAvailable" uiAccess="false" />     'the line you need to paste it to
          </requestedPrivileges>
    Code (markup):
    from the comment copy any permssion you want and paste it before the ending requestedprivileges tag and delete the old lne there.

    This wll give you permissions to have admin rights and to change or delete folders from anywhere in the computer.
