Alternatively, you can delete files in the Trash Can via a command in a Terminal. Go to Menu --> System Tools --> LXTerminal (or Ctrl+Alt+T) and type (or Copy and Paste): rm -r .local/share/Trash Info from Linux and Web Development
Sometimes, the things in the Trash Can have root privileges and you cannot delete them. The answer is another command: sudo rm -r ~/.local/share/Trash/files/*

In most cases; you may skip the Trash Can all together by selecting the item(s) you’d like to remove, pressing and holding down the [Shift] key on the keyboard and tapping the [Delete] key. This brings up a dialogue box that asks if you want to delete. You may click “Yes” with the pointer, or keep it on the keyboard and just hit the [Enter] key as “Yes” is already selected.
RECOVERY SOFTWAREIn case you’ve deleted something by accident, there is some hope with recovery software. Two you might try are PhotoRec and TestDisk.
