Excel 2010: VBA How to replace Application.FileSearch

[Hitchy]

Hello,

Having to move some files that were written by somebody else many years ago from Excel 2003 to 2010, files contain FileSearch that no longer works in 2010.
Searched and found https://www.mrexcel.com/forum/excel...tions-replacement-application-filesearch.html which includes code from Mohammad Basem, however with my limited knowledge I am unable to modify the code accordingly. Can anybody help?

Sub fileCheckForNewFiles()
    fileCheckNewCancelTime
    DirName = Workbooks(ThisWorkbook.Name).Worksheets("Setup").[DirName]
    ArchiveDirName = Workbooks(ThisWorkbook.Name).Worksheets("Setup").[ArchiveDirectory]
    With Application.FileSearch
        .LookIn = DirName
        .SearchSubFolders = False
        .Filename = "*.csv"
        .MatchTextExactly = True
        .FileType = msoFileTypeAllFiles
        
        If .Execute() > 0 Then
            If Workbooks(ThisWorkbook.Name).Worksheets("Setup").[FileInDir] = True Then
                For n = 1 To .FoundFiles.Count
                    DirName = Workbooks(ThisWorkbook.Name).Worksheets("Setup").[DirName]
                    SelectedFileName = .FoundFiles(n)
                    SelectedFileName = Right(SelectedFileName, Len(SelectedFileName) - Len(DirName) - 1)
                    
                    If SelectedFileName Like "*.Defects.csv" Then
                        FolioNumber = Left(SelectedFileName, Len(SelectedFileName) - 12)
