If your Windows PC Recycle Bin is full, when you delete a file or folder, Windows deletes it permanently. This is because there is no free space to save the item on the Recycle Bin. Another condition when deleted items are deleted permanently is if the items' size is larger than the max size of the Recycle Bin. Finally, if you reconfigure the Recycle Bin to not move items into it, all deleted items will be deleted permanently.
