When you right-click a file in Windows Explorer and select Properties from the shortcut menu, a dialog box displays basic properties for that file, including such things as file name, file size, and the file creation, last access, and last modification dates. In addition to these basic properties, the Windows operating system also tracks a number of extended file properties. These properties are typically hidden; to display them in Windows Explorer, you must click View, click Choose Details, and then select the desired properties from the resulting dialog box.The Shell Folder object includes a GetDetailsOf method that allows to access these extended properties.

The working set of a process is the set of memory pages currently visible to the process in physical RAM memory. These pages are resident and available for an application to use without triggering a page fault. While increasing your working set size can reduce paging for your application, it can adversely affect the system performance.VFP is know in using all the memory it can get. One of proactive steps in reducing memory usage is limiting VFP buffers size using SYS(3050) - Set Buffer Memory Size. It's a good idea to empty the working set when your application goes into a wait state. It can be done by calling EmptyWorkingSet Function or SetProcessWorkingSetSize Function and uses GetCurrentProcess Function
Visual FoxPro ODBC driver was last updated around VFP6 SP3. It supports a subset of VFP 6.0 features but not any new ones introduced in VFP7 and later. See VFP 6.0 Help file and Unsupported Visual FoxPro Commands and Functions (Visual FoxPro ODBC Driver) for additional information. It'll not recognize any tables that use VFP7 and later new features and either ignore them or give an error when trying to access them.
