Protecting an Entire Folder of Workbooks

Mahesh has a number of Excel workbooks, all stored in the same folder. He wonders if it is possible to assign a password to the entire folder so that all the workbooks are protected.

The short answer is no, you can't do that in Excel. There are a number of different techniques you can apply that will provide the desired result, however. The first method is to use a program such as WinZip to combine all the workbooks into a single zip file. This file can be password protected (in WinZip) so that not everyone can open it. You could then open the zip file (using your password) and double-click on any workbook in it in order to modify it with Excel. The result, for all intents and purposes, is that you have a "folder" (the zip file) that is protected, while the individual files it contains are not.

Another approach is to place the workbook folder on a network drive and then have the network admin protect the folder. Most network operating systems allow administrators to control who can have access to specific folders and their contents.

A third approach is to use a third-party program to protect the folder. A quick search of the Web will no doubt turn up several candidates, such as the following:

You can also use an Excel macro to protect the workbooks. While it does not offer true folder-level protection, it does allow you to protect all the workbooks in the folder in as easy a manner as possible.

Sub ProtectAll()
    Dim wBk As Workbook
    Dim sFileSpec As String
    Dim sPathSpec As String
    Dim sFoundFile As String

    sPathSpec = "C:\MyPath\"
    sFileSpec = "*.xls?"

    sFoundFile = Dir(sPathSpec & sFileSpec)
    Do While sFoundFile <> ""
        Set wBk = Workbooks.Open(sPathSpec & sFoundFile)
        With wBk
            Application.DisplayAlerts = False
            wBk.SaveAs FileName:=.FullName, _
              Password:="swordfish"
            Application.DisplayAlerts = True
        End With
        Set wBk = Nothing
        Workbooks(sFoundFile).Close False
        sFoundFile = Dir
    Loop
End Sub

Make sure you change the sPathSpec and sFileSpec variables, near the beginning of the code, to reflect the folder containing the workbooks and the pattern for the names of the workbooks you want protected. The macro assumes that all the workbooks are unprotected; if any are not, the macro will prompt for the workbook's password.

Excellent piece of code...mainly because it was the solution that came to mind :). Actually, I looked to see if there were a better method than I would have used. Your newsletter is a must read list every Monday AM, when I first see it.

FWIW, another use for a FoundFile Do Loop is to process a series of input report files to aggregate into a larger report. In those cases, filename validation (e.g. the department name, report name, date would be part of the file naming standard) and file content validation (e.g. worksheets that meet a naming standard, headers on a worksheet, character string (e.g. report name)in a specific place) are used to identify if the input file should be used and how it should be used.
