I've lost track of the number of times I've gone to a folder (say, my home folder), selected the View Options (View > Show View Options), then carefully set the "sort by", the "icon size", the setting for "show item info", the background texture, etc. -- only to come back to it later (after what critical operation or change I don't know) and find that all the settings have been changed, back to some dopey unsorted view - not what I set them as! This has been a problem in past versions of the OS and it continues in Yosemite. It's SO annoying! Somewhere I got the impression that a folder's "View Options" settings are stored in an invisible file in the folder called .DS_Store ? If I have that right, is my problem that the .DS_Store file keeps on changing, or being corrupted somehow? If so, why? Would it be OK to set up a folder as I want it and then lock its .DS_Store file ? I'd love some help with this. It sounds a bit trivial, but really it's so annoying having to go back time and again and configure the settings.
