You can use putty to ssh into the OS shell. This is the best way to gain access. Once you are in you will need to be made "su -" once you have admin rights the prompt should be "#".
"ls /" will give you a list of directorys located on the snap.
"ls /tmp" will give you a list of files in the tmp directory. adding a -l (ls /tmp -l) should give you long file attributes. adding "|more"

v4 has locked a lot of cmds out.

"cd /tmp" should change you to the /tmp dir (no longer works in v4)

then you need to diside which one you want to remove.

"rm <filename>" should be the cmd to remove the file
or "rm /tmp/<filename>

use "exit" to back out, may need to enter it twice.


NOW I DO NOT KNOW WHAT WILL HAPPEN ONCE YOU REMOVE A FILE. SO USE AT YOU OWN RISK. Maybe someone with better linux skills will be able to add.
