Win10 Pagefile
Win10 Pagefile
After Vista, Windows delays using the pagefile until memory is scarce or needs to reorganize free space in RAM. Since memory stays organized, you might have a lot of free space but it can't accommodate large programs because fragments prevent forming a continuous 500MB block. The operating system must clear and rearrange RAM pages, creating a large available area for your program. Even with enough total free space, fragmentation can block the process from running properly. Some memory-heavy tasks may exceed their limits or shared memory boundaries, forcing them to rely on the pagefile despite having sufficient overall availability.
