![]() ![]() #OMNIDISKSWEEPER NOT SHOWING ALL FILES MAC OS#Anyway it took me a lot of googling to find the mysterious missing storage, as even if you enable hidden files, Mac OS is still pretty sneaky and won't let you access them and hence find out the amount of space they are utilising/wasting. #OMNIDISKSWEEPER NOT SHOWING ALL FILES INSTALL#The reason this all came about was that I was trying to install windows on a boot camp partition and the free space available for this was less than I wanted, after clearing some unused files, I gradually realised that there was some missing storage space on my primary drive: windows doesn't seem to be able to be installed on a 2nd drive that I have in my MBP (I swapped out the optical drive, moved the 500gb HD to the optical bay and stuck a 250gb SSD in the original HD slot and used it as my primary boot drive - but that's another story). I use a 3Gb time capsule for backups so have no need of this huge amount of space being wasted on my MBP's drive. Even the MobileBackups folder, that you quite rightly say is a normal part of time machine local backup files, contains 63Gb as you can see. I fiddled around with terminal commands and time machine settings and ended up with a file called ash that was taking up 63Gb of my SSD. This will create folder in top directory of hard disk (double click on ssd or hd image to open into this directory) called “trash me” That contains the mobile ash files to be deleted.ĭefaults write AppleShowAllFiles TRUEĭefaults write AppleShowAllFiles FALSE Obviously it will need amending to delete any other files you want rid of. To delete the ash file I used this command in Terminal. See following article to explain further about this step: However in my case, I didn't have enough space for the time machine back up so disabled it but then ended up with a hidden file called MobileBackups.Trash that took me ages to find using the above process and then delete (as I will explain in a bit). MobileBackups file is a Time machine back up file that will usually be deleted once Time Machine has backed up to an external file. ![]() MobileBackups file that wont be shown by Omnidisk sweeper or similar App if run from users directory. In my example there are 68.3 GB taken up by the. (Must be run as User with Admin privileges). I used OmniDisk Sweeper (free App) with the above command to run it from the root directory, should look something like this, showing all files, hidden or otherwise and file sizes. You will then be required to enter your password. Sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper To view, you need to run OmniDisk Sweeper or similar from the root directory (very important as it will not show all the hidden files or other users files if run as I guess most people - myself included - run it, that is from their user directory) You also need to be logged in as an Administrator. However, knowing this and finding the pesky hidden files took me a lot of googling and a fair amount of time, repairing disk permissions and disks had no effect whatsoever, so here is the solution if your boot drive seems to have used space that you cannot accont for, or "lost space": It seems it is usually due to hidden files and particularly those related to mobile backups from Time machine. If your HD or (as in my case SSD) is reporting via Finder or Omnidisk sweeper or similar App that the used space is greater than the files that you can account for (ie my 250GB SSD was showing in Finder as having 134Gb of used space but the sum of all the files reported by Omni disc sweeper, Finder and Disk inventory X only came to 64GB with just over 50Gb of free space: hence 70GB that I could not account for or find. I confess that this is not my work but a few cobbled together solutions from others that worked for me. ![]() I thought I would post this as I spent a lot of time finding the solution and came across a lot of threads for the same problem, so hope it helps some people out. ![]()
