Thanks Sergey.

>It has been changed in VFP8 help:
>"To increase the number of applications that you can run simultaneously, Microsoft Windows supports virtual memory by swapping segments of code (code that is the least recently used) from RAM to the hard disk in the form of a paging file. As a rule, the default settings in the Windows operating system for managing virtual memory meet the requirements of most users; these settings are recommended.

>Windows NT and 2000 already have permanent swap files. Take a look at Optimizing your Swap file (PAGEFILE.SYS) http://www.tek-tips.com/gfaqs.cfm/pid/96/fid/3876

>>Hi all,
>>
>>In VFP 7's help for Configuring the Operating Environment, there is a line that states:
>>
>>The swap file does not improve Visual FoxPro performance and is not a substitute for more RAM. If you do need a swap file, make sure you create a permanent one rather than a temporary one."

>>In Windows NT, what is the difference and how to set a permanent swap file? How about Windows 2000, is it any different?

>>TIA.
