I have documents (pdf, txt, etc.) and photo files in the persistent storage of my Tails USB and I edit them using editors such as Libreoffice, Scribus, Okular, etc.(I always use tails OS in offline mode. I never connect to the internet.)

However, some of these documents and photo files must be taken out from this persistent storage to another external hard drive later.

These files taken out to an external hard drive will be moved to my other main laptop for routine use(and of course the internet).

I have a question here, do these files(pdf,txt,jpg,etc.) that were edited in Tails and taken out from Tails have traces of the Tails os?

I never want to be caught in the presence and use of Tails os.

Please exclude my tails USB itself(because no one knows its existence), can the existence and use of Tails Os be discovered through those files or the laptop?(In the extreme, if someone do forensics for those files or laptop).

If so, is there any way to completely remove the traces of presence and use of Tails OS from those files?
