Let the user select a directory (as workingdirectory, or for save/load data to/from, etc.), which is also known as a "Browse for Folder" function. This is the most easy way to provide this feature, just using the standard Common Dialog control.
Assumes
Start a new VB5/6 project, and put a CommandButton and a CommonDialog control on
the form. Paste in this code and you're ready to go.

VBcoders'Browse For Folder - the easy way
'
'Providing your users an elegant method of selecting a folder(as working
'directory, or to save/load files to/from, or....) is often desired, but
'hard to implement. Cumbersome SHFileOpen routines, or complicated
'hand-made alternatives are needed. Pardon... were needed.
'Although it is said at several places, including Microsoft (!), you can't
'do "Browse for Folder" with a Common Dialog control, I'll show you it can be
'done. Quick and Easy. And with very familiar interface to the users, including
'all standard options for navigating and browsing - even creation of a new folder
'and use of network paths.

CommonDialog1.Filter = "Folders|*.~#!"
'This reads as "show the user 'Folders' as filetype", while the files-filter
'is specified as being an impossible filetype. This causes the dialog to show
'folders only (as there's no matching file found).
CommonDialog1.CancelError = True 'allow escape key/cancel
CommonDialog1.ShowSave 'show the dialog.
'Note: ShowSave has more approperiate button captions then ShowOpen in this case.

sMyNewDirectory = CurDir 'CurDir has been changed to the selected one
MsgBox ("Directory selected: " & sMyNewDirectory) 'Show the result
