Check if files exist based on list of cell values - excel

Question

I need to check if a list of files exist in a certain directory, based on cell values in Excel.
If some files are not found, a message box displays the names of the files that were not found.

Answer 1

I'm unclear if you want to see the files listed in the range that do not appear in the folder or if you want to see the files in the folder that are not in the range.
The following example lists the files in the range that are not in the folder.
I've set up a page for the example, so you may need to adjust your sheet to match, or adjust your code to fit your sheet. Be sure that the folder path you put in B1 has the trailing backslash.
Here's the code:
Sub files_in_folder()
Dim folder As String
Dim filename As String
Dim filenames As Range
Dim cell As Range
Dim s As Worksheet
Dim missing As New Collection
Dim message As String
Dim x As Integer
Set s = ActiveSheet
folder = s.Range("b1").Value
Set filenames = Range(s.Range("b2"), s.Range("b2").End(xlDown))
For Each cell In filenames
If Dir(folder + cell.Value) = "" Then missing.Add cell.Value
Next
If missing.Count = 0 Then
message = "All files were found in " & folder
Else
message = "The following files were not found in " & folder & vbNewLine
For x = 1 To missing.Count
message = message + " " + missing(x) & vbNewLine
Next
End If
MsgBox message
End Sub

Try this.
Sub TestListFilesInFolder()
' Open folder selection
' Open folder selection
With Application.FileDialog(msoFileDialogFolderPicker)
.Title = "Select a Folder"
.AllowMultiSelect = False
If .Show <> -1 Then GoTo NextCode
pPath = .SelectedItems(1)
If Right(pPath, 1) <> "\" Then
pPath = pPath & "\"
End If
End With
Application.WindowState = xlMinimized
Application.ScreenUpdating = False
Workbooks.Add ' create a new workbook for the file list
' add headers
ActiveSheet.Name = "ListOfFiles"
With Range("A2")
.Formula = "Folder contents:"
.Font.Bold = True
.Font.Size = 12
End With
Range("A3").Formula = "File Name:"
Range("B3").Formula = "File Size:"
Range("C3").Formula = "File Type:"
Range("D3").Formula = "Date Created:"
Range("E3").Formula = "Date Last Accessed:"
Range("F3").Formula = "Date Last Modified:"
Range("A3:F3").Font.Bold = True
Worksheets("ListOfFiles").Range("A1").Value = pPath
Range("A1").Select
With Selection.Interior
.Pattern = xlSolid
.PatternColorIndex = xlAutomatic
.Color = 65535
.TintAndShade = 0
.PatternTintAndShade = 0
End With
With Selection.Font
.Color = -16776961
.TintAndShade = 0
End With
Selection.Font.Bold = True
ListFilesInFolder Worksheets("ListOfFiles").Range("A1").Value, True
' list all files included subfolders
Range("A3").Select
Lastrow = Range("A1048576").End(xlUp).Row
Range(Selection, Selection.End(xlToRight)).Select
Range(Selection, Selection.End(xlDown)).Select
ActiveWorkbook.Worksheets("ListOfFiles").Sort.SortFields.Clear
ActiveWorkbook.Worksheets("ListOfFiles").Sort.SortFields.Add Key:=Range( _
"B4:B" & Lastrow), SortOn:=xlSortOnValues, Order:=xlDescending, DataOption:= _
xlSortNormal
With ActiveWorkbook.Worksheets("ListOfFiles").Sort
.SetRange Range("A3:F" & Lastrow)
.Header = xlYes
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
End With
Range("A1").Select
Cells.Select
Cells.EntireColumn.AutoFit
Columns("A:A").Select
Selection.ColumnWidth = 100
Range("A1").Select
NextCode:
MsgBox "No files Selected!!"
End Sub
Sub ListFilesInFolder(SourceFolderName As String, IncludeSubfolders As Boolean)
' lists information about the files in SourceFolder
Dim FSO As Scripting.FileSystemObject
Dim SourceFolder As Scripting.Folder, SubFolder As Scripting.Folder
Dim FileItem As Scripting.File
Dim r As Long
Set FSO = New Scripting.FileSystemObject
Set SourceFolder = FSO.GetFolder(SourceFolderName)
r = Range("A1048576").End(xlUp).Row + 1
For Each FileItem In SourceFolder.Files
' display file properties
Cells(r, 1).Formula = FileItem.Path & FileItem.Name
Cells(r, 2).Formula = (FileItem.Size / 1048576)
Cells(r, 2).Value = Format(Cells(r, 2).Value, "##.##") & " MB"
Cells(r, 3).Formula = FileItem.Type
Cells(r, 4).Formula = FileItem.DateCreated
Cells(r, 5).Formula = FileItem.DateLastAccessed
Cells(r, 6).Formula = FileItem.DateLastModified
' use file methods (not proper in this example)
r = r + 1 ' next row number
Next FileItem
If IncludeSubfolders Then
For Each SubFolder In SourceFolder.SubFolders
ListFilesInFolder SubFolder.Path, True
Next SubFolder
End If
Columns("A:F").AutoFit
Set FileItem = Nothing
Set SourceFolder = Nothing
Set FSO = Nothing
ActiveWorkbook.Saved = True
End Sub
Result:
