Hello,
I am trying to navigate within the file system using C programming. Here I
use system( “cd [folder]” ) e.g. to navigate into a desired folder. When
this folder exists, system() returns “0”; when it doesn’t exist system()
returns e.g. “256” AND prints out an error message like “sh: cd: [folder] -
no such file or directory” on the active terminal window.
How can I suppress this error output on the screen?

use chdir() instead of system()…
Or, if you insist on using system(), try redirecting its standard output
and standard error elsewhere…

But system(“cd folder”) is not going to change your program’s directory.
It’s going to start a shell that changes its directory and then exits.
