You're speaking as if this will help you. If you go to the prosecution/trial phase, you will be found guilty since you probably hadn't the best opsec and forensic analysis of your computer found the encryption/steganography software you used, or you left something in the system logs (e.g. timestamps of accessing files), or you left something in the thumbnail cache, or you did not rename the file before deleting it, or the timestamp analysis of e.g. you browser data and logs will show clear behavioral patterns pointing to you hiding data. If you use VMs, their ram is stored in a plaintext file unless you configure it otherwise, on your ssd it never goes away due to wear protection. Even if you had an encrypted drive you will be forced to give them the key, then they will rederive the master key and analyze parts of the disk free space to find something on you, again on ssd this is a certainty and on for example Bitlocker you can never change the master key, ensuring you going to jail.
Even if all of this did not incriminate you, you're in trouble for something in the first place, since you're on trial, right? So probably other people you communicated with lead them to you. And in this case, the judge applies common sense, there is this traffic cell of 6 people and on 5 computers we have clear evidence but on 6th nothing, therefore you're still probably 95+% guilty? Judges aren't stupid.
People making comments like yours annoy me since you seem to be calming people down that we could endure total strong encryption ban, while we absolutely could not.
