I have a lot of log files in a folder and would like to be able to rename the (.log) to (.txt) and
then combine all of them into one txt file.

I can use the dos command CD c:\logfiles ren *.* *.txt     to rename the all the ext's but how can i run a script that will combine all the files into one.

Thanks,

Have you tried using copy?

cd c:\logfiles
ren *.* *.txt
copy *.txt Newfile.txt

You can call it through vb using Shell:

Private Sub Command1_Click()
ChDrive "C:\"
ChDir "C:\logfiles"
Shell Environ("Comspec") & " /c copy *.* C:\NewFile.txt", vbHide
End Sub

You can also type this on the command line

type *.txt > new.txt

You could also add a filelistbox and loop through it adding the contents of each file into a new file:

Private Sub Form_Load()
File1.Path = "C:\logfiles"
End Sub

Private Sub Command1_Click()
Dim tFile As String, NewFile As String, Ln As String
Dim ff As Integer, nf As Integer, i As Integer

NewFile = "C:\Newfile.txt"

nf = FreeFile
Open NewFile For Output As #nf

For i = 0 To File1.ListCount - 1
tFile = File1.Path & "\" & File1.List(i)
ff = FreeFile
Open tFile For Input As #ff
Do Until EOF(ff)
Line Input #ff, Ln
Print #nf, Ln
Loop
Close #ff
Next i

Close #nf

End Sub

File1.Path = "C:\logfiles"

the files are in this folder, not sure what's going on.

Just add a Filelistbox to your form.It should be in your vb toolbox on the left.It looks like a document icon.

On the components tab, there is a control called FileListBox, just add it to your form and name it File1.

You might also want to keep this control invisible at runtime. Depends on your requirements.
