Find files that were not accessed in the last x days

Question

how can i find all files that were not accessed in the last 10 days with extension ".png"?

This is a question of my homework but i'm not getting it right

I tried find / -type f -mtime -10 -name "*.png" but it's not right

Answer 1

You should use -atime for access time and +10 for greater than 10 days:

find / -type f -atime +10 -name "*.png"
