  2. Memory paging - Wikipedia

    en.wikipedia.org/wiki/Memory_paging

    Windows 3.x creates a hidden file named 386SPART.PAR or WIN386.SWP for use as a swap file. It is generally found in the root directory, but it may appear elsewhere (typically in the WINDOWS directory). Its size depends on how much swap space the system has (a setting selected by the user under Control Panel →

  3. zram - Wikipedia

    en.wikipedia.org/wiki/Zram

    Using compressed swap space with zram or zswap also offers advantages for low-end hardware devices such as embedded devices and netbooks. Such devices usually use flash-based storage, which has limited lifespan due to write amplification, and may also use it to provide swap space. Using zram or zswap reduces the swap usage, which effectively ...

  4. Filename mangling - Wikipedia

    en.wikipedia.org/wiki/Filename_mangling

    In this case, the filenames become mangled by taking the first six non-space characters in the filename and adding a tilde (~) and then a number to ensure the uniqueness of the 8.3 filename on the disk. This mangling scheme can turn (for example) Program Files into PROGRA~1.

  5. Disk partitioning - Wikipedia

    en.wikipedia.org/wiki/Disk_partitioning

    Each partition can be formatted with a file system or as a swap partition. Multiple partitions allow directories such as /boot, /tmp, /usr, /var, or /home to be allocated their own filesystems. Such a scheme has a number of advantages: If one file system gets corrupted, the data outside that filesystem/partition may stay intact, minimizing data ...

  6. List of RAM drive software - Wikipedia

    en.wikipedia.org/wiki/List_of_RAM_drive_software

    1) the mounted space of ramfs is theorically infinite, as ramfs will grow if needed, which can easily cause system lockup or crash for using up all available memory, or start heavy swapping to free up more memory for the ramfs. For this reason limiting the size of a ramfs area can be recommendable. 2) tmpfs is backed by the computer's swap space

  7. Defragmentation - Wikipedia

    en.wikipedia.org/wiki/Defragmentation

    These files can be safely moved when the operating system is not in use. For example, ntfsresize moves these files to resize an NTFS partition. The tool PageDefrag could defragment Windows system files such as the swap file and the files that store the Windows registry by running at boot time before the GUI is loaded. Since Windows Vista, the ...

  8. Resident set size - Wikipedia

    en.wikipedia.org/wiki/Resident_set_size

    In computing, resident set size (RSS) is the portion of memory (measured in kilobytes) occupied by a process that is held in main memory ().The rest of the occupied memory exists in the swap space or file system, either because some parts of the occupied memory were paged out, or because some parts of the executable were never loaded.

  9. Virtual memory - Wikipedia

    en.wikipedia.org/wiki/Virtual_memory

    Virtual memory combines active RAM and inactive memory on DASD [a] to form a large range of contiguous addresses.. In computing, virtual memory, or virtual storage, [b] is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" [3] which "creates the illusion to users of a very large (main) memory".
