Use a Path Substitution

Instead of specifying the full path to data files in your system, you can use a path substitution.

With path substitution, you use a name that is a substitution for a full directory path. You can then use the substitution name in the following format:

For example, if you decide to store a trend data file in the default data directory, you could specify the full path to the file:

Or you could use a default path substitution and specify the following:

Path substitution provides greater control of data storage. You can change the location of data files by changing the definition of the data path - instead of locating and changing each occurrence of the data path.

A set of default path names are listed below. You can also define your own path substitutions using the parameter [Path]<PathName>.

Note: You will need to manually configure the access control list for a folder specified in a path substitution so that it matches the permissions that were applied to the default location during installation. See Configure Directory Security for Modified Folder Locations.
