I have 93.1GB for my windows partition or drive, however, I have no idea why there is so little usable space (1GB left), is there any software here that takes up so much space and can be removed harmlessly? I only use mathematica, microsoft offices, python, and in principle all others are redundant. Is it true that i have many software development libraries installed but can be removed?

My Vista 64 installation has drive C, a 150 GB hard drive.  I also has a 1.5 TB drive D.  My C drive has 12.3 GB free.  I don't know what's using up all the space.  There's almost 83 GB unaccounted for!!!  As per  question and  question, I downloaded  and .  WinDirStat, once I found the right options, tells me there's 82.9 GB of .  SpaceMonger, which has a particularly nice display of the data, tells me there's 82.3 GB "Unscanned", with 2 unscannable folders.  Where do I turn now?  Both tools roughly agree there's a large amount of data on my drive, but neither seem to be able to tell me what.  I've tried the standard approach; disk cleanup, remove hibernation file, set the virtual memory to the D drive instead of the C drive.

There is only one partition for both system files and personal data, which is C:. The other two partitions are for boot and for recovery.  Now I have two different reports on the size of C: on my Windows 7:   by clicking the property of C:, it shows 59.4 GB for "used space"; by selecting all contents (I have setup to view all hidden files and directories) under C: and viewing their property, it shows 46.9 GB for "size" and 47.6 GB for "size on disk".   Here are my questions:   I was wondering why the two reports are not the same, and where the difference comes? in the second way, why "size" and "size on disk" are different? What do they mean actually? What is the difference between them and "used space" in the first way?   Thanks in advance!

My Ubuntu cloud server has left only 900MB of disk space.   I'll just empty the directory /tmp and wondering if there is any other location to clean up.

I'm going to install 64 bit 14.04 on a new machine with something like 1 to maybe 128GB RAM and even more RAM later. How much space should I allocate to the swap partition?   And especially: WHY those recommendations for these numbers?    (None of the existing answers  and  explain any of the why and are a bit dated if we look at 1GB or RAM and up)

my disk has over 100GB of free space, but the usage bar in Computer is displayed in red, as if it reached a low space limit. It looks like Windows applies the same 10% or 15% hard disk space value for low space warnings, regardless of if the disk is 50GB in size or 1.5TB, which is not very smart and obsolete for most recent computers.  Is there a Registry key or some place I can change this percentage so the usage bar displays in green, not red?  The hibernation and page files are already reserved (5GB together), so surely the low space warning for a 1.5TB disk should be 5-10GB, not 150GB or more. The way Windows 7 computes the low space limit seems pretty dumb, not much Intellisense there.  This is not a high priority issue, but it makes the Computer applet look pretty stupid and it's irritating every day to see that 100GB of free space is putting my computer in the red. It would also be nice to be able to edit this low limit percentage in Computer/Manage/Storage/Disk Management or directly in the disk properties ("Tools" tab).

How can I visualize which folders and files are taking up all of the space on my hard drive?  I'm getting some conflicting reports on the size of hard drive contents. Namely what is and isn't there and what folders are actually using the space.   I need to know which of the files or folders the culprits behind all this hidden bloat. Also there should be a print option to get it on paper.

I am getting a 50% larger "Size on Disk" than the "Size" of files would lead me to expect, as linked. I have some idea from other posts that I have read about cluster size and small file allocation to clusters causing waste but would that account for 300GB extra space used/wasted?    Any ideas on how I could resolve this disparity and reduce the Size on Disk please?

I have some unallocated space before my Windows 7 partition.    Can I move the Windows 7 partition so that the free space is after it instead than before it, and then extend the partition to use all of the currently unallocated space?

I have a 1TB* external HDD which comes out at 931GB total space on windows explorer (run as admin).  When I look at free space it lists only 183GB free with 747GB used. However, there is not this much used space. When using WinDirStat (run as admin) this drive only uses 472GB of space.  I have cleared the shadowstorage down to the latest shadowstorage using DiskCleanup which increased the free space to the 183GB free. Now I can't think of anything else  that could be causing this 275GB discrepancy.   I had used this external drive on an old laptop, could there be an issue with that?   Thanks for any advice.

I have a Win7 laptop with a 750Gig C: drive.  It came partitioned with 714Gig usable from manufacturer.  I installed programs, music files, etc up to 285 gigs.  As of a few weeks ago it showed 285 Gigs.  Two weeks of house guests later and it shows HD is full.  I deleted some files but it still shows 652 Gigs on this drive while there are only 285 Gigs on drive.  Relevant details:   I am Administrator on laptop and have fair knowledge of what I am doing. I did not restore from backup, restore from mirror, upgrade HD's or anything else that would have touched the partition structure.  Just daily use as imaging machine and web. I have checked partitions under disk administrator - no change, still partitioned with 714Gigs usable. Have looked through computer C drive by hand showing Hidden files and folders - no change. I have used JDisk Report to double check - it shows I have only 285 Gigs on C drive. I triple checked with TreeSize run as Administrator and it also shows 285 Gigs on C drive - yet Windows 7 still shows almost full. I used Windows 7 Utilities to Check for Disk Errors, and Defragged the drive.  No errors shown and no change after Defrag.

Can anyone help explain why there is 17 GB worth of free space on my LVG I can't seem to do anything with this space. Is there anyway to fix this? I have already reformatted the disk then cloned the contents back with CCC. I also have FileVault enabled.  Whenever I see this on others setups it is usually a few KB not 17 GB

In typical PCs the Size of Windows Folder is 6 to 8 GB but in my Case its 25GB. How can I delete the unwanted files from the Windows Folder (which, in turn, will optimize my C Drive size).  My system is Windows 7 with 60 GB in C Drive with 59 GB occupied.

I am using Linux. And within an uncontrolled event, my 4GB system disk is full.  When I try to uninstall some program by sudo apt-get purge program-name, it gives me this error:  /usr/bin/mandb: can't write to /var/cache/man/25843: No space left on device   Is there any system file that can be deleted in this situation?

I have my Windows partition (C), 9GB of free space and then I have my Linux partition. How do I expand my Linux partition with that 9GB of free space using Gparted and without losing everything I have?    If this is not possible, is there another tool (safer one) that I can use?

I cleared space on my disk by deleting files and emptying trash. But, I am unable to make use of the space that I freed up. That is, as you can see the disk reports 142 GB as Available with 83 GB of that as purgeable.    So I should have plenty of space to to copy over a 70 GB file onto the disk. Yet when I try I get an error stating "Not enough disk space to copy", like the following image shows:    How do I clear out the purgeable space to make it truly available for use?  I've tried rebooting in the hopes that a restart clears out the purgeable area, but had no change trying that.

I have only one disk in my computer, a 80 GB SSD. It is formatted as a single ext4 partition (no swap), and all the usual folders are installed on it (I keep lots of data on external media, but /home and all the rest is on the SSD).   Today I booted it and I got a message that the drive is full. I opened Disk Usage Analyzer to look at what takes up space. It insists that 67.8 GB of the disk are used, and that / is taking up 36.4 GB. Which leads to the question, where are the missing 30 GB, if not on the file system?!    Just to have a comparison, I added up all the sizes of all readable folders listed in Nautilus as subfolders of / (including the hidden ones). I got 20.9 GB. Trash was unreadable, but I know it has 16.2 GB, so the sum is 36.1 GB, around the same as what Disk Usage Analyzer is reporting. There were some system folders which were unreadable, like proc, but I doubt that they add up to 30 GB - else it wouldn't be possible to install Ubuntu on small disks, and I've seen it run on 2.5 GB. I think they must be the 0.3 GB difference between my calculation and the Disk Usage Analyzer's report.   So I'd like to know, what is eating up these 30 GB and how do I get it to free them?     Edit with answers to CYREX's questions   Booted from Ubuntu 10.10 64-bit live CD (same as my system).  fsck result:   root@ubuntu:~# fsck /dev/sda1 fsck from util-linux-ng 2.17.2 e2fsck 1.41.12 (17-May-2010) /dev/sda1: clean, 265956/4890624 files, 18073343/19537408 blocks  Booted from the SSD. Emptied the trash, and the 16 GB from there are now free. The 30 GB are still missing.    I'm not experienced enough to know what counts as weird in a log. Here are my messages log and my syslog since last boot. Maybe you can find something in them:       Here it got really strange. I plugged in an external 500 GB HDD. Disk Usage Analyzer overreported the available space, then showed space missing (76 GB used, but only 24 in folders).      Booted again from the LiveCD, started the Disk Usage Analyzer from it and got the same results as from the installed Ubuntu, within 1-2 GB.   Edit with answer to CodeMonk:  That would have been a nice solution, but the partition is really 80 GB - I mean 74 GB + marketing "error", anyway the whole disk is formatted. It also shows that over 50 GB are used, so where are the 30 GB if not in files and folders?    GParted also reports the correct size of the external HDD.
