OK. I have also seen and held in my hand documents and reports that had once been classified top secret, but had been declassified. They were stamped and no longer in the same classified folders. The photo you refer to of classified folders laying on the floor is where they pulled some out, laid them out on the floor for the photograph. Anybody that thought they were found that way, was nutso. I certainly did not. It was striking, simply as being a basically low level guy, I have never seen more than one classified folder at a time in one setting, any time, anywhere. Somebody in echelons above reality (as we used to say) may shuffled them like playing cards for all I know, but if so, so far above my level, I never saw it. Like you said, there was a decommission SCIF there for his use but hardly a long term storage SCIF. Any locked room can be used as a SCIF for viewing or reading or working with a classified file that requires it if there is a guard set up preventing access to other than authorized personnel. Not all SCIFs are used for storage and certainly not for storage after someone no longer has the need to know access requirement, as at that point of decommissioning all would be removed. The room where the bulk documents were was at one time a storeroom for molding used for the outside of Mar-a-Lago, some people described as a closet in the basement, that just to have the files not taken back earlier, the FBI requested an additional lock be put on the door and it appears that it was. As for classified marked folders found in the desk of Trump's personal office at Mar-a-Lago, that certainly was not a SCIF for proper secure storage. It is just not how it is done. I do not know what was in those folders and neither do you, and unlikely we will ever know in completeness, as that is the nature of top secret file security. You can believe the best or the worst, the most innocuous or the most damnable and nobody will confirm or deny, because that is the way it is.
