Problem with file-based databases (Paradox, DBase) under Windows Vista and Windows 7.

The problem consists in access to the file C:\PDOXUSRS.NET, which is used by the Borland Database Engine (BDE). It is caused by improved security in Windows Vista and Windows 7. Access to files in the root directory of the system drive (typically C:\) is secured more than in earlier versions of Windows. It is recommended that you create a new directory, e.g. C:\BDE, and specify this directory as the value of the Paradox driver's NET DIR parameter via BDE Administrator (program bdeadmin.exe) (see the screenshot below). Note: The file system permissions of the BDE directory need not be set to "Read only".
