Assigning password to all files

[nachiketdp]

Hi all,
I have a directory containing several folders and sub-folders. I want to write a macro for assigning a common read-only and read-write password to all the files in the directory(regardless of the file types).

I already have a code for doing this for excel workbooks. I tried to modify it for all files,but in vain.
Can anyone help me on this? Following is the aforesaid code for excel workbooks.

Sub Password_assigner()
Dim strDirectory As String, bSubFolders As Boolean
Dim fs As FileSearch, i As Long, strPW As String, strPWRW As String
Dim wb As Files, wbFF As Files
Dim iSubs As Integer
Dim ws As Worksheet
pq = 1
Application.DisplayAlerts = False
Application.ScreenUpdating = False
Set wb = ThisWorkbook
bSubFolders = False
Set fs = Application.FileSearch
strDirectory = GetFolder()
iSubs = MsgBox("Include Workbooks in sub-folders?", vbYesNo, "Sub-Folders")
If iSubs = vbYes Then bSubFolders = True
With fs
    .LookIn = strDirectory
    .SearchSubFolders = bSubFolders
    .FileType = msoFileTypeExcelWorkbooks
    If .Execute > 0 Then
        strPW = Application.InputBox("Enter read-only password to apply", "Read-only Password", Type:=2)
        strPWRW = Application.InputBox("Enter read-write password to apply", "Read-write Password", Type:=2)
        ThisWorkbook.Worksheets("Error").Columns("A:A").Select 
        Selection.Delete Shift:=xlToLeft
        For i = 1 To .FoundFiles.Count
            nameoffile = .FoundFiles(i)
            On Error GoTo errorhandler
            Set wbFF = Workbooks.Open(.FoundFiles(i), UpdateLinks:=False, ReadOnly:=False, Password:="")
            If gprs = 1004 Then gprs = 0: GoTo bnu9
            wbFF.SaveAs .FoundFiles(i), , Password:=strPW, writerespassword:=strPWRW
            wbFF.Close
            Set wbFF = Nothing
            bnu9:
        Next i
    Else: MsgBox "No Workbooks found": Exit Sub
    End If
End With
ThisWorkbook.Worksheets("Error").Cells(1, 1).Value = "Files to which password could not be assigned"
If pq = 1 Then ThisWorkbook.Worksheets("Error").Cells(2, 1).Value = "Not a single file"
ThisWorkbook.Worksheets("Error").Cells(1, 1).Font.bold = True
Application.ScreenUpdating = True
MsgBox "Operation Completed"
Exit Sub
errorhandler:
If Err.Number = 1004 Then
    pq = pq + 1
    ThisWorkbook.Worksheets("Error").Cells(pq, 1).Value = nameoffile
    gprs = 1004: Resume Next
Else: Resume
End If
End Sub

Function GetFolder() As String
Dim fldr As FileDialog
Dim sItem As String
Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
With fldr
    .Title = "Select a Folder"
    .AllowMultiSelect = False
    .InitialFileName = Application.DefaultFilePath
    If .Show <> -1 Then GoTo NextCode
    sItem = .SelectedItems(1)
End With
NextCode:
GetFolder = sItem
Set fldr = Nothing
End Function

Thanks in advance,

Not all file types are going to be capable of being password protected.

Hi Aaron,

Thanks for your reply. I wasn't knowing that it cannot be done for all types of files. Atleast can I achieve it for all MS office files?
