So I was using Photoshop and i started getting messages from photoshop that my scratch disk is full. Then I started getting messages from my mac that my start up disk is almost full... But its not. According to Disk Utility, about this mac, finder, and get info... I have nearly 400GB of free space... Why is it giving my low disk space errors when I'm using less then 10% of my hard drive?

You use your mac as a single partition?

my start up disk is a single 500GB SSD with only one partition. I have a second 3TB drive that i use for files and that is not even 30% full either.

the error tells me my startup disk is full. I've even tried omnisweep that says i have 400 gb free as well
[doublepost=1473208257][/doublepost]okay... this has something to do with photoshop... for some reason when I try to crop or do any processing on a photo my hard disk shows as being full all with other... I close photoshop and its back to normal/

Could you use grandperspective and see how much space each folder/file uses?
Since you are elcapitan there is no such "purgeable" space issue, the one I recently research when using Sierra.

okay.. so I've determined that its Somthing related to photo shop... My mac doesn't ever give me the error until I get the scratch disk thing on photoshop. So I tried switching photoshops scratch disk to my other drive... then when I try to crop an image the loading bar stops in the middle... if i check disk utility when this is going on it says my hard disk is full.. then if I quit photo shop it goes back to normal.

So Photoshop uses up 400GB of your free space when cropping images?
