To use the IPT you must select a directory where the IPT will store its configuration information – called the IPT data directory.
Please select an empty, writable folder or an existing IPT data directory. Do not select a folder that is vulnerable to other processes, such as /tmp, which may be emptied on a system restart. This folder should be backed up regularly in keeping with a disaster recovery plan.
For example, use a path such as "C:\datadir" for Windows environments or "/srv/datadir" for Unix-like environments such as Linux, Mac OS X.
