Saving pictures from iphone SE 3rd Edition to PC

[learninmypc]

Using a USB recharge cord I plugged my iphone into my HP desk top to save my pictures to a folder on my desktop. Clicked start saw apple phone is the menu clicked it & several folders popped up,copied ALL of them, clicked CUT cause I wanted them OFF my iphone. It took about 5 minutes, to paste them in folder. Once done, opened my iphone to see all 400 plus pictures STILL there, I DID A CUT & PASTE yet it did not cut, it copied. Any reason what went wrong???

Using the same exact USB recharging cord, plugged it into a USB thing on my desktop, plugged other end into my iphone , clicked the file explorer folder , it shows Apple iphone so I clicked on it & up came multiple folders, moused over them & CLICKED the scissors icon showing CUT, I did so. Went to empty folder on desktop & right clicking I clicked PASTE, it did such, once done I went to my iphone & STILL SEE 676 items left. What good are scissors if they DON'T CUT ?? Am doing this because I saw a red mark on my settings thing telling me I have 9.44 GB of space left.. Am baffled
