Trying to load some photos from a card, keep getting messages that there's no room...

Hey Mac gurus...

I have a Macbook Air running OSX El Capitan version 10.11.6
I use my machine mostly to process photos, email, web surf, things like that...so no real heavy hitting here.
I have, what I think is the 250GB HD, and for some reason I can't load any more photos because there's no room.
I don't know if it's my backups, or messages, or something that is consuming my drive...but I don't know how to see what's what like I can on my iphone or my old PC. Can someone tell me where and how I can find out how my storage is being used, and how to delete files I don't need anymore?
I have been using my external drives to move photos now, but I really want to get them onto my machine and photoshop a few from some recent trips for my folks...

PS - I used to do the disk defrag and disk cleanup on my old PC, is there something similar to do maintenance wise on my Mac? This is my first one, so any advice would be greatly appreciated...

Help please!

Thanks

Whatever you do, don't attempt to defrag an SSD. Doing so will damage it.

For other maintenance there is OnyX. Make sure you get the correct version for your OS.

Click to expand...

- Apple Menu
- About This Mac
- Click on the "More Info" button.
- Click on the "Storage" tab (near the upper left of the window).

This will show you free space.

No defragging because the MacBook Air has solid state storage (this rule applies to Windows computers too).

As far as maintenance. Download & install the free app called "Onyx". Just click on the "Automation" tab.

HTH,

And with info I leaned from you, too.

Download Grand Perspective. It will give you a graphical view of your SSD. The bigger the square, the bigger the file.
