Public Function CompareFiles (FilePath1, FilePath2)
Dim FS, File1, File2
Set FS = CreateObject(“Scripting.FileSystemObject”)
If FS.GetFile(FilePath1).Size FS.GetFile(FilePath2).Size Then
CompareFiles = True
Exit Function
End If
Set File1 = FS.GetFile(FilePath1).OpenAsTextStream(1, 0)
Set File2 = FS.GetFile(FilePath2).OpenAsTextStream(1, 0)
CompareFiles = False
Do While File1.AtEndOfStream = False
Str1 = File1.Read(1000)
Str2 = File2.Read(1000)
CompareFiles = StrComp(Str1, Str2, 0)
If CompareFiles 0 Then
CompareFiles = True
Exit Do
End If
