I am using the Raspberry Pi 3. I want to modify the file (increase the limit of files) limits.conf in /etc/security/limits.conf, but when I try to save the file after modification, it gives the error [Can't open file to write].

Since the file limits.conf is only writable as the root user, you must launch nano as root using sudo. For example:
$ sudo nano /etc/security/limits.conf
