Copy Set Cells From Multiple Workbooks Into 1

As an answer to a post about vba script for consolidating workbooks based upon pre-defined cells,

Sub ConsolidateDate()
Dim wbDst As Workbook
Dim wbSrc As Workbook
Dim wsDst As Worksheet
Dim wsSrc As Worksheet
Dim I As Long
Set wbDst = ThisWorkbook
Set wsDst = wbDst.ActiveSheet
With Application.FileSearch
.NewSearch
.FileType = msoFileTypeExcelWorkbooks
.LookIn = "C:Myfolder"
For I = 1 To .FoundFiles.Count
Set wbSrc = Workbooks.Open(.FoundFiles(I))
Set wsSrc = wbSrc.Worksheets("Data")
wsDst. Range("A" & I) = wsSrc.Range("A2")
wsDst.Range("B" & I) = wsSrc.Range("C6")
wsDst.Range("C" & I) = wsSrc.Range("D7")
wsDst.Range("D" & I) = Dir(.FoundFiles(I))
Next I
End With
End Sub

I was hoping someone could translate the meaning of this code for me, I am a beginner with using VBA and I am trying to write VBA script for a similar task I am working on. The references to cells A2, C6 and D7 were used as an example of cells to be copied.
