1. Save a file to a folder.
2. Check to see if the file exists.
3. If it does, append a sequential number to the file name.
4. Check to see if that file exists.
5. If it does, increment the sequential number to the file name.
Loop this process until a file name does not exist in the folder.

Example:

contents of c:\temp  -->  test.txt    test1.txt    test2.txt

save test.txt in c:\temp

   does test.txt exist?  Yes, rename to test1.txt
   does test1.txt exist?  Yes, rename to test2.txt
   does test2.txt exist? Yes, rename to test3.txt
   does test3.tst exist? no, save as test3.txt

Hi seckel,

This logic will never end, as you rename test.txt to test1.txt it will be there so will be renamed again as test2.txt and so on until you reach the largest number you can.

Are you really looking for a way to save a file with the most recent sequential number?

Just need to check for test.txt first...
Try this...(assuming you've got your data you want to save in the file...I used strData of "My Text")

fname = Split("test.txt", ".")
strData = "My Text"
ext = "." & fname(1)
fname = fname(0)
strName = fname
If Dir("C:\temp\" & fname & ext) = fname & ext Then
    x = 1
    Do While Dir("C:\temp\" & fname & x & ext) = fname & x & ext
        x = x + 1
    Loop
    Open ("C:\temp\" & fname & x & ext) For Output As #1
        Write #1, strData
    Close #1
Else
    Open ("C:\temp\" & fname & ext) For Output As #1
        Write #1, strData
    Close #1
End If

Dim MyFile as String
Dim TargetFile As String
Dim i as Integer
MyFile = Dir("C\:Test.txt")
TargetFile="C:\Test1.txt"
i=1
Do While i<=3
If MyFile<>"" Then
   Name MyFile As TargetFile
Else
     Msgbox "File not found
     Exit Do
End If
i=i+1
MyFile =Dir(TargetFile)
TargetFile = "C:\Test" & i & ".txt"
Loop

Good attempt, but all this did was overwrite test.txt with "My Text".

I need a to save a file but not overwrite existing files.  If the file name exists, I want to save the file with a numeric extenstion.

Are you certain?
I ran it here with no problem...
The code states that if a Dir of C:\temp\test.txt returns successfully, then begin the procedure to append a number to it, so I don't see how this wouldn't have worked...
Can you try stepping through the code and determine if that first If statement suceeds or not...
