i want to use vba to count all the lines in all the files in all the subfolder of a directory and display them in a cell. how do i do that?
i found a code working for counting the lines in a single file. but i dont know how to construct the loop to apply this to all the files in all the subfolder




<code style="margin: 0px; padding: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; vertical-align: baseline; box-sizing: inherit; white-space: inherit;">Function countLF(fName As String) As Long
Dim st As String
Open fName
For Input As #1: st = Input(LOF(1), 1): Close

countLF
= Len(st) - Len(Replace(st, vbLf, "")) + 1
End Function

=countLF("c:\test.txt")</code>

Re: how to count the total llines in all files in all subfolders

Below is a code which will create a list of all files in a selected folder from the active cell down (start the macro called ScanFilesInSubfolders)
Then you can use the filenames to get the line count any way you like (I think your code will not always work)
Code:
Option Explicit
Option Compare Text
Option Base 1


Private cRng As Range 'current cell - increasing with every new record


Sub ScanFilesInSubfolders()
    On Error GoTo errHandler
    
'Select folder to be scanned
    Dim root As String: root = BrowseForFolder
    If UCase(root) = "FALSE" Then Exit Sub 'if no folder is selected
    If Left(root, 2) = "\\" Then MsgBox "Cannot scan network drives yet!", vbOKOnly: Exit Sub
    
    If Right(root, 1) <> "\" Then root = root & "\" 'make sure we have \ at the end
    Dim AbsLevel As Long: AbsLevel = UBound(Split(root, "\")) - 1 'directory depth of root in the drive
    Dim RL As Long: RL = 0 'relative directory level - root=0
    Dim drv As String: drv = Left(root, 1)
'    Dim ColHeaders As String: ColHeaders = "Object,Name,Extension,Type,Size,Full path,Parent folder,Relative level,Attributes,Date created,Date Modified,Date accessed"
    
    Dim i As Long, j As Long

    Dim wb As Workbook
    If Not ActiveWorkbook Is Nothing Then
        Set wb = ActiveWorkbook
        If MsgBox("All files will be listed down from the ActiveCell. Do you want to continue?", vbYesNo + vbQuestion) = vbNo Then Exit Sub
    Else
        Set wb = Workbooks.Add
    End If
    
    i = 0

When you run it you will get a dialog box to select the folder.

Re: how to count the total llines in all files in all subfolders

ok it writes the list of files to active cell. now how do i store these names into variables or an array and run an if statement with the code i posted at the top to count lines in file in case its txt? sorry for needing you to do everything for me. im not very experienced in vba

Re: how to count the total llines in all files in all subfolders

Why would you bother with code?
Your post shows that you want to use it as formula.
So if the filenames list is in column A starting from A1, then simply put this formula in column B starting from B1:
Code:
=countLF(A1)
if your function works properly you will see the results in column B

If you still want to incorporate it in the code for any reason, try this:
Code:
Option Explicit
Option Compare Text
Option Base 1

This is a perfect code!
May I ask, how to make it as a function to call in a cell and extract just the number of files up to the deepethed subfolder?

Thanks for your assistance.
