Can i delete this file ?

Hi,

On my linux system i find the below two files which occupy good space.

Code:
# du -sh /root/myswapfile /swap2
1.1G    /root/myswapfile
1001M   /swap2

# ls -ltr /root/myswapfile /swap2
-rw-------. 1 root root 1073741824 Jan 27  2017 /root/myswapfile
-rw-------. 1 root root 1048576000 Jan 31  2017 /swap2

Current output of top command:

Code:

Considering my current memory usage is it safe to remove (rm) any of the two files ?
