Tech is coming to do some work on cable/wireless tomorrow. Too many pics to transfer to USB, how can I hide or protect personal pics from a tech savvy stranger?
Create a password protected archive. Won’t stop the determined or resourceful but the tech guy is probably neither. Be sure to delete the originals after you test the archive.
Assuming a stock home windows installation; you may not be able to pw protect a file or archive. But, you can still create an archive, rename it, and bury it on the drive. Not perfect, but better than nothing.
Select the folder(s) and right-click. Choose Send To from the menu and select Compressed (Zip) Folder. Rename the folder to something like e8GWYGo3DWdDHW and bury it somewhere like C:\Windows wain_32\system mp. Create some subfolders if necessary. Delete the original files. Later, fish the file out, rename it to a .zip file and extract.
Not going to assume this is what the OP is talking about but I’m thinking personal nudes would be a type of “porn” one wouldn’t want the tech checking out.
