How many times have you gotten half way down the page typing and something has happened that made you lose the whole thing? It has happened to me many times (unfortunately). If you are using Microsoft Word it does have a back up and recovery feature, but it isn’t foolproof, you still can lose a lot of work.
There are many other programs that may be used on a daily basis that don’t have this recovery feature. One rule of thumb is to save right away and then save every 5 or so minutes. I suggest every time you are done with another paragraph or a big change click that save button or press CTRL + S.
Get to know your keyboard shortcuts and use them. It saves a lot more time pressing two keys, the CTRL + S keys (for you Mac people Command + S), with your fingers already near them then to raise your hand up, put it on the mouse and move it to the save button. It’s painless and easy.
A lot of programs, like Microsoft Word, have fail-safes. In Word’s case it’s an auto save so if something was to happen and the computer restarted usually some of the lost data will be recovered. Other programs, like TextPad, don’t have an auto save.
Don’t be upset again with losing valuable data. Use your save button often.
