While I can move files using drag / drop in PIXEL, how do I copy a file to a new folder and leave the original in place. With Windows you just hold CTRL down. Doesn't work in PIXEL. Are there 'instructions' for this anywhere?
I presume you are asking how to copy files in
PCManFM which is the default File Manager in the latest Raspbian GUI. (
PIXEL is the name of the Desktop Manager “Pi Improved Xwindows Environment, Lightweight”.)
You can copy files with the
Edit/Paste Menu items, more conveniently using
Ctrl+V shortcut keys, which are the same as Windows.
There are other File Managers, and you can more conveniently copy files in the terminal using
cp source_file target_file.
