To find out if a file exists on a disk you can use the Visual Basic Dir() function. It has the following syntax: Dir[(pathname[, attributes])] In this context, pathname would be the name of the file that you are trying to find. The Attributes can be one or more of the following values (separated by the OR operator) Attribute Description vbNormal Default Attribute vbReadOnly Use if file pathname is read-only vbHidden Use if the file pathname is hidden vbSystem Use if the file pathname is a system file vbArchive Use if the file pathname is an Archive file vbDirectory Use if pathname is a directory Example: If Dir(myfilename, vbNormal or vbReadOnly or vbHidden or vbSystem or vbArchive) = "" then     Call Msgbox ("This file does not exist") Else     Call msgbox ("This file does exist") End If
