Q: Wasting Disk Space

Hi folks,

 

I've installed iCloud 5.0 on a Windows 8.1 /64Bit Maschine.

My goal is to have a copy of my Photos from three iOS Devices on my PC. Im using the iCloud Photolibrary not the Mediastream.

 

My photolibrary has an amount of 18GB.

 

Now my problem:

 

The folder "C:\Users\username\Appdata\Local\Apple Inc\CloudKit\iCloud Photos\MMCS has an amount of 145GB and counting.

Has anyone an idea what is going on?

 

Thanks a lot for any replies.

Udo

    I have exactly the same issue. Windows 10 64 bit, iCloud 5.2. My 250 gig drive lost all disk space. Downloaded and ran the wonderful free utility WinDirStat that pointed me to the culprit - the Cloudkit MMCS folder with hundreds of files, dating back from today to more than a month ago and each 500 mb. These are clearly temp files, they are much larger than the overall size of my iCloud storage which is 25 gig. I deleted them all except for those with today's date and freed up 150 gig.

     

    This is clearly a bug - Apple has a cleanup routine somewhere that is failing for certain users, so older files are not getting deleted. This is fairly recent - as nothing was dated more than 2 months ago. So I suspect a bug in a more recent version of iCloud.


    I will monitor this and report back, but it's highly unlikely that deleting any of the older temp files will cause any problem whatsoever, while running out of disk space on your primary drive can lead to a total system crash,  corrupted operating system etc. I strongly urge those running out of disk space to delete the older temp files to prevent a system crash from happening. Hopefully, Apple is aware of this bug and will fix it in an upcoming release.

    So here it is July 27th and CrApple still hasn't fixed this issue. Typical dumb *** programmers who can't see a blunder when it goes live let alone in testing, and no one in charge there cares enough to push a fix thru. Suck my hairy balls CrApple.

    I just found a customer's computer with this problem. Theirs is actually 777GB!! They have a 1TB hard drive and now it's maxed out and Windows 7 is not booting anymore. Lovely. The files are dated within about a 3 week span. I'm sure if I delete the files the computer will be unusable again in another 3 weeks.

     

    Why does this happen?
