Windows uses the swap file to improve performance. A computer normally uses primary memory , or RAM , to store information used for current operations, but the swap file serves as additional memory available to hold additional data. Note: Microsoft recommends that you allow Windows to manage the Virtual Memory settings for you i.
Only experienced users should change this setting, as it can adversely affect system performance. Also note that you can manually move the location of the swap file to a different drive. In some situations, this can be advantageous. Hi Thomas, Ask are you refering to Hard drive or Network drive? Do you get any error message? From which location are you trying to open this drive?

Select Properties. On the Advanced tab, click the Settings button underPerformance. Victorias Grathwol Professional. Do you need a pagefile with 16gb of RAM? By default Windowswill allocate virtual memory pagefile the same size asyour RAM. It will "reserve" this disk space to ensure it'sthere if required.

Virtual memory is a memory managementcapability of an operating system OS that uses hardware andsoftware to allow a computer to compensate for physical memory shortages by temporarily transferring data fromrandom access memory RAM to diskstorage.
Yacouba Pyzewsk Pundit. What is page file space? In storage, a pagefile is a reserved portion of ahard disk that is used as an extension of random access memory RAM for data in RAM that hasn't been used recently.

The whole point is that when an app requests a block of memory it may see itself being given a block of real memory. In reality only part, or none at all, of this could be 'real' with the rest stored temporarily virtualised on the hard drive.
If an app requests memory that's stored off in this virtual world, a 'page fault' is generated, the virtual memory is swapped over to real memory in chunks called 'pages' and everything carries on. The primary reason why this is a helpful thing is found back in the days when the amount of real memory a processor could access was limited to mere megabytes.
The virtual memory system typically works on pages of 4K, which are swapped in and out of real memory as a whole. This enabled a processor that could be limited to just 4MB of real physical memory to address potentially gigabytes of virtual memory, albeit with that data store on a hard drive.
Even today systems with 2GB of memory can easily require virtual memory and with the majority of people running bit versions of Windows, 4GB is the practical physical memory accessible.
