Swap file is used to “expand” the memory RAM, so increase the capability to execute more softwares at same time. In a GNU/Linux, it’s possible to create a dedicated swap partition or use a file.
Below I’ll show step by step how to create a Swap file in a Linux OS.
With this feature activated, will be possible to run many applications and keep the unactive process in “stand-by” in HD or SSD while you can play any heavy game or execute a HTTP or FTP service.

# sudo su
# su –
01 – Create swap file
# dd if=/dev/zero of=/swap bs=1M count=1024
02 – Give write permission to file
# chmod 600 /swap
03 – Create a swap area
# mkswap -f /swap
04 – Add Swap file to Linux startup
Add swap configuration to “/etc/fstab”. Modify the file with something like this:
# nano /etc/fstab
05 – Test
First restart your machine and run the follow command:
If you get a result like below, everything worked ok!
