Sorry, I should have given you a sample usage of this:<br />
<br />
&nbsp;Dim vFile As String<br />
&nbsp;vFile = FirstFileName(&quot;C:\folderna<wbr />me&quot;)<br />
&nbsp;If Len(vFile) &gt;&nbsp;0 Then<br />
&nbsp; Workbooks.Open vFile<br />
&nbsp;End If<br />

I have an Excel file in a folder with a name that will often change. I need to open that file and copy contents from it to another Excel file. I have the macro written to perform all the tasks, except if I don't know what the name of the file will be when the macro is run, so how can I open it? &nbsp;It will be the only file in this folder, and the folder name will never change. &nbsp;Is there a command line that will rename the file (without knowing what that file name is) if I know the folder name?

A macro command that will open an unknown file in a known folder?

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
