OS X V10.7 Lion :: Hard Drive Space Being Used As A "preview Document"?
Jun 19, 2012
I'm assisting a friend with an issue that now perturbs me. He came to me noting that his HD has suddenly seen a huge jump in used space. I've seen that before due to several complications, so I needed to narrow it down. We also checked common issues, such as:Trash not emptied (he's rigorous on that)iPhoto separate Trash not emptied (he doesn't use iPhoto, but after checking it's got nothing as it is)Downloads not emptied (he provided me with the existing DL folder space, below. It's tiny relative to the space in question)Mail attachments issue: ~/user/Library is small. After asking for some extra information, I have this to start:
Surprisingly, "Other" is not the item causing the issue, or signifying it, which is usually the case for things like the recursive-Mail attachments issue. To double check, I also asked him to provide me with the ~/user contents so I could see if there was any mismatch. Note: HE IS THE ONLY USER ON THIS HARD DRIVE. He provided me with: APPLICATIONS 36.2mbDESKTOP 12.73mbDOCS 27.32mbDOWNLOADS 994.3 mbDROPBOX (synced to online only)GOOGLE DRIVE 414mbLIBRARY: 11.46gbMOVIES 783mbMUSIC 94.19 gbPICTURES 365 gb ~PUBLIC 0mSITES 0m
Hence his confusion, since his pictures are showing as ~185GB smaller in his User than the stated size in the About This Mac. Note, the ~/user/Library folder is relatively in line with normal sizes, maybe a bit bigger (I checked, App Support is the main driver of this), but not the size we'd need to be taking up ~300GB. We were also able to glean this information through a third party app, it recognises an additional 193GB in "preview document" items, that, as you can see below, when broken down into the individual files appear to be mere copies of existing master images:
(The selected segment in the upper right, Preview Document, is then broken down in the bottom left. It's almost entirely pictures)
Now I was under the impression Preview/Versions only take up a miniscule space on the HD since they don't FULLY copy the master file, they more create a bridge between the two that amounts to a few MB. Is it possible that it's taking up a much larger amount than intended here (a la the same basic mail attachment problem, but with Preview)? If so, what directory would that be located in?
We have ALSO searched /Volumes to see if there's any hidden/phantom volume that was created and is eating up space. No such thing found, only MacHD and MobileBackups, which is showing as 0kb. In lieu of any other solution in future I might consider trashing it, but we'll see.
We're currently re-indexing the Mac HD to see if we get any major changes in the numbers. Failing that, I'll be running an HD and permissions verification from the recovery system just to be sure. Once the index is done, I'll also have to check the other MacHD/master folders, i.e. System and Library and so on, in case there's something about them to tip me off--including simply being larger than expected.
Again, I am a bit confused as I've never seen the space-eating problem be relegated to images alone, nor described as "previews". This one's new to me. So, what am I missing/not noticing/in need of?

I previously had a Windows 7 Boot Camp partition of roughly 50GB on my 256GB MacBook Air. I removed this partition after Wind'ohs driving me crazy after a while. However, now my Mac partition is only 200GB, and I'm not able to increase its size. Also, my Recovery HD shows up in permanently in Finder and Disk Utility.I now need to (sadly...) reinstall Windows, but Boot Camp won't partition my drive, giving me the error: "The startup disk cannot be partitioned or restored to a single partition". What's going on with my partitions? The Recovery HD seems to be causing the problem, but I don't understand why I can't use the 50GB of space that is empty.
After installing a new version of java I discovered that my hard drive had lost about 55Gb of space, I emptied the trash and gained about 8 Gb. As Iwrite this I am watching my HD space decrease by about .01gb every 10 seconds. I Am in the process of using Time Machine to restore to a time before the upgrade. Well that didn,t work as it has just told me that there isn't,t enough space to copy my hd.

I am giving my son my old macbook air, and wanted to free up as much hard drive space as possible. I deleted my user account, and I expected there to be about 225 GB of free space. There is not, however. When I check the storage, it says there is nearly 78 GB of "Backups." My question is whether that backup is from my old account, and ultimately, where can I find this to delete it to free up the space.
I also have another macbook air that I plan to sell. What is the best way to erase the contents of the computer without deleting the OS. I plan to sell it, and obviously don't want the next purchaser to have access to my old data.
I have a mid 2011 21.5" 2.7 GHZ I5 IMac with a 1 TB HDD. It is reporting that the startup disk is full (<8gb left). I have surveyed the hard drive and found the "users" folder is using 972GB.The sole "user" folder (me) is using 972 GB An exploration and sum of "folder size" of each of the underlying folders (there are 8: Audio books, Desktop, Documents, Download, Movies, Music, Picture and Public) collectively sums to 316,6GB. The system tool in "about the iMac" (storage tab) shows "other" allocated a 893,97GB. Where is the missing 640GB plus of space? Please can anyone advise me how to identify where space has been allocated and how to rectify the problem?
I have done the following: All updates are installedVerified the partition - no faultsTimemachine - never been activatedre-indexed spotlight as suggested in a support article.deleted a dormant user (6GB) and deleted their dataI have emptied the trash. What else can i do?

I have a MacBook Air with 251 GB of hard drive space, yet I only have 3 gigabytes free. I checked all my folders and they certainly do not add up to 248 GB, so where is all of this coming from? I checked my activity monitor and there is nothing that drastically large neither.
I'm finally getting used to the extra steps required to save a doc in Preview now (but I hate it). What I'm noticing now is that when I open a document in Preview, it also opens the last doc I viewed at the same time..If I wanted to see the old doc I would've double clicked it.I use Preview all the time.There is no Preference to disable this strange behavoir.
I only have like 8 gb left on my macbook's hard drive. Are there any programs I can run that will defrag/free up space? How much does Apple Store typically charge to upgrade a hard drive? How easy is it to do myself?
This is what im trying to do. I have a macbook with 120gb hard drive. thats not enough space from my music collection. So i was wondering how to make itunes run off a external hard drive. I looked around and found was for a PC.
I have been running out of hard drive space and have deleted a whole bunch of files... even deleted all the languages i didn't need from all my applications... about a week ago i freed up around 2GB.... but without saving and downloading anything my free space is now 70MB!! All I have been doing is watching streamed videos and I notice this reduces the drive space as I'm watching it!! Even opening firefox and some websites drops my memory by 0.1MB. I can't find anywhere where temporary files might be so i can delete them.
I never used to have this problem but I wonder if it has something to do with the fact that I now use wireless internet through a phone provider and a USB modem rather than my previous WiFi via cable broadband. Can anybody shed some light on what is stealing my memory when browsing?
Last time I checked I had at least 6gb free space left, and over night, it went down to 0kb. I even deleted some things and it was up to 2gb. After awhile, it went back down to 0kb. I really don't want to get a new HD, because for some reason my Tiger disk won't read, so that's a little pricey there for both a new HD and Tiger.
Trying to turn on FileVault I get a message saying: There isn't enough space on your hard disk to turn on FileVault. Turning on FileVault requires an additional 132.2 GB of free space on the volume "Macintosh HD". Try emptying the Trash or deleting files you don't need.
Finder says that hard drive "Macintosh HD" has a capacity of 499.76 GB and that 180.42 GB are available. Am I to understand that to run FileVault I would need 312.62 GB (132.2 + 180.42 GB) empty on a 499.76 GB hard drive?! Seems crazy! Might this be related to Parallels 6 or something?
When you bought your MBP how much space did you have available out of the box. My 80 gig hardrive has a capacity of 74.21 and I never checked how much was used when I bought it. Reason I am asking is, I have 42.4 gigs left and I cant figure out where all that space went. I can account for 9 gigs worth of itunes music and videos, and maybe another 4 or so gigs of other stuff. What about the rest? How do I check if I have a HUGE plist file or something?
When I bought leopard and installed it I was left with about 3 gigs on my hard drive so I deleted final cut studio 2 and Adobe Photoshop, however when I did this I checked my free space on my hard drive and it didn't free up anything and I know that it should have given me over 60 gigs of free space.
I have a Mac Book Pro with 148 GB of Hard Drive space (about 24 BG available). I have about 30 GB used up from Apps and random files, but I cant figure out what is using up the other 100 GB. I know the OS takes up space, but not that much.
I have 120 giga in my hard drive and as you can see "Other" takes most of the disk space.
And these are my files and their size with take 49.22 giga of space, I don't see where is the rest of the disk space. I believe it is in the "Other" but how can I access it to free the not needed items.
I have a new Macbook Pro that I just got in May and my hard drive is pretty full (only about 20gb left), but I have NO idea what is taking up so much space. Is there an app that lets me see in a list what exactly is hogging so much space on my computer?
It seems like I'm always fluctuating between 2 and 9 gb of free space on my hard drive. Every time I need lots of space it seems to disappear, then it reappears in a week. Is this normal? If I'm low is there something I can run to bring this space back?
Running Snow Leopard on a Late 2007 MacBook, and I booted it up today to see that I had 15 GB left (normal). 4 hours later, I get an alert that I'm running low on Hard Disk space, so I open a new Finder window to see how much space I have. It tells me 10 MB. After 5 minutes, this dropped down to 0 KB, and all of my applications opened "paused", and I had to force quit them. I don't have 0 KB left, I have 15 GB, but Finder isn't telling me that.
I have a 500GB external hard drive that is partitioned into 3 sections -  Mac OS extended for dedicated time machine backups (200GB),  Mac OS extended for general file storage (100GB) and  FAT32 for backing up my husband's windows PC (the rest). I've been doing some video editing and moving clips between the external HD and my macbook. But now I've finished I noticed that something weird has happened. The Mac partition of the external HD currently has only 3 files, around 1.2GB. But Finder is showing 77GB is used and therefore not letting me copy my DV footage (around 40GB) that I want to transfer to a friend's computer.
I've put a screenshot here - and have hidden files/folders displayed. So what is taking up the 76GB that finder says is used?
