A system with a smaller page size uses more pages, requiring a page table that occupies more space. For example, if a 2 32 virtual address space is mapped to 4 KiB (2 12 bytes) pages, the number of virtual pages is 2 20 = (2 32 / 2 12). However, if the page size is increased to 32 KiB (2 15 bytes), only 2 17 pages are required. A multi-level ...
The entries in the page directory have an additional flag in bit 7, named PS (for page size). If the system has set this bit to 1, the page directory entry does not point to a page table but to a single, large 2 MB page (Page Size Extension).
Intel 5-level paging, referred to simply as 5-level paging in Intel documents, is a processor extension for the x86-64 line of processors. [1]: 11 It extends the size of virtual addresses from 48 bits to 57 bits by adding an additional level to x86-64's multilevel page tables, increasing the addressable virtual memory from 256 TiB to 128 PiB.
Since PageDefrag only affects a few files, it takes a relatively short time to run when compared to entire-disk defragmenters such as Windows Defrag, so long as the page file is not fragmented. If the page file is fragmented, PageDefrag can take as long or longer than Windows Defrag. However, a defragmentation of the page file can improve ...
In the default configuration of Windows, the page file is allowed to expand beyond its initial allocation when necessary. If this happens gradually, it can become heavily fragmented which can potentially cause performance problems. [15] The common advice given to avoid this is to set a single "locked" page file size so that Windows will not ...
File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte. A large value is often expressed with a metric prefix (as in megabyte and gigabyte) or a binary prefix (as in mebibyte and gibibyte). [1]

The maximum file size Notepad can open depends on operating system limitations on the size of the EDIT window class, with a different limit in each version of Windows. Because of this limitation, on Windows 3.0 , Windows 3.1 , and Windows 3.11 , Notepad could not open files larger than 54 KB .
