• Path can be an absolute or relative reference.
• On Windows systems, changing the default directory doesn't change the default drive; it changes only a particular drive's default directory.
Example sNewDir = "c:\program files\my folder\" ChDir sNewDir
ChDir ".." 'c:\program files is now the default directory.
Programming Tips & Gotchas
• Remember that on the Apple Power Macintosh, the relative notation "::" moves to the next higher folder, whereas on Windows 95 and NT, the notation is "..".
• On Windows systems, the relative notation "." represents the current directory.
• On Windows systems, the relative notation ".." represents the parent of the current directory. If the root directory is the current directory, the statement:
doesn't change the current directory and doesn't produce a syntax error.
• On the Apple Power Macintosh, ChDir changes both the default directory and the default drive.
• On Windows systems, the current drive is unaffected by ChDir. For instance, if the current drive is C:\ and you issue the statement:
the current directory on drive D: is changed to D:\MyFolder, but the current drive is still C:\.
• If path isn't found, a trappable error, 76, "Path not found," is generated. However, if path refers to another machine on the network, error 75, "Path/ File access error," is generated.
• Although you can use a network path such as \\NTSERV1\d$\TestDir\ to change the current directory on the network admin share \\NTSERV1\d$, you can't access this drive using ChDrive without having the drive mapped to a drive letter, which makes using network paths with ChDir a little pointless!
• Use CurDir to determine the current default directory for a particular drive.
• If you are using VB6, you will find that the new File System objects offer much more flexibility than the intrinsic drive and directory statements.
