I am in a habit of using [Shift] + [Del] combination to delete files rather than delete only. I won’t store not-so-important files in my Recycle Bin, that’s why. This is a good habit in one hand and bad in the other hand because there’s a chance I accidentally delete an important file/folder. Luckily, Linux (Ubuntu in this case) has few good tools to recover deleted data and in easy ways.
