Hello, this is the virtual memory of the system. When the physical memory is insufficient, the virtual memory will be used. If there is no problem in use, it is not recommended to delete it. cannot be deleted directly
Check out the virtual memory file actually used now:
cat /proc/swaps
or
/sbin/swapon -s
To see if virtual memory is now used see the Swap line:
free -m
