swap file
Hi, can anybody tell in simple terms, what is the swap
file and how it affects the memory? regards |
The swap file is a file on the hard drive that is used when there is
insufficient memory (ram) to do the operations being run on the PC. This is called paging which is a technique used by virtual memory operating systems to help ensure that the data you need is available as quickly as possible. The operating system copies a certain number of pages from your storage device to main memory. When a program needs a page that is not in main memory, the operating system copies the required page into memory and copies another page back to the disk. -- Regards Ron Badour, MS MVP for W98 Tips: http://home.satx.rr.com/badour Knowledge Base Info: http://support.microsoft.com/default.aspx?pr=kbinfo wrote in message ...

And windows maintains a swapfile, even if you have more tha adequate
physical memory to perform all processes called upon. "Ron Badour" wrote in message ...

A very important point that Dave added. Windows will build a swap file but
if you have sufficient physical memory installed, the swap file will not be used--it just takes up space on the drive. That is the ideal situation as the swap file is tremendously slow as compared to ram. -- Regards Ron Badour, MS MVP for W98 Tips: http://home.satx.rr.com/badour Knowledge Base Info: http://support.microsoft.com/default.aspx?pr=kbinfo "Lil' Dave" wrote in message ...
