Very minor but same way/reason you need to "defrag" your computer hard drive now and then, or re-format discs/disks in the old days. Anytime you delete off of digital/magnetic media there is often a few stray bits left behind (usually at a start or end of a file section) or intentionally left as "markers". Formatting clean these off and starts fresh. Of course, in this day & age of 64 or 128Gb cards, a few bits aren't important. Was just making the point that formatting MIGHT add space versus lose it as the original post stated.

These are always entertaining threads.

When I buy a car I don't look for the one that does everything, but I do look for the one that does everything I want/need.

I look at software the same way. I don't need a package that does everything, just one that does what I need.

I'm pretty sure based on what I read in the forums and images I see that a good percentage of folks never learn 10% of whatever software they are using. Buying the "best" software, like buying the "best" camera, doesn't make your images better.

How old were the contestants? If they were Gen-Xers or Millenials, World War II consisted of about a three paragraph description in their history books. In my daughter's high school history book, the Viet Nam war merited a single paragraph. If there was a Jeopardy question on which President ordered the bombing of North Vietnam or what was the capital city of South Vietnam, they would't have the faintest idea what the answer might be. Oh yeah, as a Baby Boomer I know that's a P-51 Mustang; probably a "D" model as evidenced by the bubble canopy.

In your first sentence, move the comma after the word "kept" to after the word "lose".
In your third sentence, use "that" instead of "which" since the noun is followed by a restrictive clause. Unless you learned British English, then you can have a pass for that one.
In your fourth sentence you need a space after the word "will". On second thought, there are so many grammatical errors in this sentence I would suggest deleting it and trying again.
In your final sentence, move the period inside the closing parenthesis. This is done when a sentence is started with an open parenthesis.
You would know all this if you paid attention in grammar school.
