Name
ChDir Procedure
Class
Microsoft.VisualBasic.FileSystem
Syntax
ChDir(path)-
path(required; String) The path of the directory to set as the new default directory

Changes the current working (default) directory.
Rules at a Glance
pathcan be an absolute or relative reference.Changing the default directory does not change the default drive; it only changes a particular drive’s default directory.
Example
ChDir("c:\program files\my folder\")
ChDir("..") 'c:\program files is now the default directory.Programming Tips and Gotchas

If
pathis not found, or a FileNotFoundExeception exception, 76, “Path not found,” is generated. However, ifpathrefers 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 directory for a particular drive.
