No, when you delete a file the operating system merely hides it from view. Deleted files can sit on a hard drive for a long time before being over written. They won't be deleted from cloud backups or storage.
Many, many years ago an employee of a non-profit wiped his laptop of every file created during his employment in an act of pettiness (that cost him in court later). For a very reasonable fee a professional recovery company was able to retrieve every file on that laptop. They were able to document exactly when they were copied to an external hard drive, when they were deleted, my clumsy attempts to retrieve, everything. There is software that will try to rewrite over the space the deleted files to hide them, but even then, the really good techs can still recover files. If you've obtained those files online, eg CSAM, there are other trails that will lead to you and it will be very hard to hide once the authorities know to look for you.
Is not enough to permanently remove sensitive data. When you delete a file, the operating system only removes the reference to the data, leaving the actual data intact on the drive until it is overwritten by new information.
As it's been said, it's not enough. CCleaner can overwrite files up to 35 times using its secure deletion feature, making them unrecoverable. Supposedly even 3 passes makes them unrecoverable.
When Hillary Clinton was trying to hide her many nefarious activities, she used a program called BleachBit to wipe her illegal server hidden in her basement. I assume that she had top IT advice on this subject.
Billary are well known to have engaged in threesomes. They would use some of Epstein's underage girls for sexual sandwiches. This is the *REAL* reason they had everything wiped clean.
But...Pam "brown nose Bondi" has done more hiding and scrubbing with the Epstein files to hide Trump's nefariois activities, than the Clintons have. They are ALL rotten to the core.
