Name Statement
Renames a disk file, directory, or folder.
Syntax
Name oldpathname As newpathname
The Name statement syntax has these parts:
Part Description
oldpathname Required. String expression that specifies the existing file
name and location — may include directory or folder, and drive.
newpathname Required. String expression that specifies the new file name
and location — may include directory or folder, and drive. The file name
specified by newpathname can't already exist.
Remarks
The Name statement renames a file and moves it to a different directory
or folder, if necessary. Name can move a file across drives, but it can
only rename an existing directory or folder when both newpathname and
oldpathname are located on the same drive. Name cannot create a new
file, directory, or folder.
Using Name on an open file produces an error. You must close an open
file before renaming it. Name arguments cannot include
multiple-character (*) and single-character (?) wildcards.
