I was trying to clean my ubuntu system and saw that most of the system directories look 100% full. Is this normal? How can I clean these (if unnecessary) files?

looking at df -h, I realized I have this /dev/loop0 mounted on /snap/core/3604 and it's always 100% full :   root@maxipc:~# df -h Filesystem      Size  Used Avail Use% Mounted on udev            7.8G     0  7.8G   0% /dev tmpfs           1.6G  9.9M  1.6G   1% /run /dev/sda3       116G   38G   73G  35% / tmpfs           7.8G   20M  7.8G   1% /dev/shm tmpfs           5.0M  4.0K  5.0M   1% /run/lock tmpfs           7.8G     0  7.8G   0% /sys/fs/cgroup /dev/loop0       84M   84M     0 100% /snap/core/3604 /dev/sda1       239M  111M  111M  50% /boot cgmfs           100K     0  100K   0% /run/cgmanager/fs tmpfs           1.6G   44K  1.6G   1% /run/user/1000   When I do a umount /snap/core/3604orumount /dev/loop0 it will unmount so it's apparently not busy at all(also when i try to remount /dev/loop0 again, it doesnt remount because, of course, it's not in fstab. in it, it looks like there is a whole little, cute and tiny root filesystem squashed in that 84M:   root@maxipc:~# ls -la /snap/core/3604 total 4 drwxr-xr-x 24 root root  333 Nov 30 12:39 . drwxr-xr-x  3 root root 4096 Dec 26 20:29 .. drwxr-xr-x  2 root root 1937 Nov 30 12:38 bin drwxr-xr-x  6 root root  129 Nov 30 12:38 boot drwxr-xr-x  4 root root 1160 Nov 30 12:38 dev drwxr-xr-x 80 root root 2399 Nov 30 12:38 etc drwxr-xr-x  2 root root    3 Apr 12  2016 home drwxr-xr-x 20 root root  406 Nov 30 12:38 lib drwxr-xr-x  2 root root   43 Nov 30 12:38 lib64 drwxr-xr-x  2 root root    3 Nov 30 12:35 media drwxr-xr-x  3 root root   45 Nov 30 12:39 meta drwxr-xr-x  2 root root    3 Nov 30 12:35 mnt drwxr-xr-x  2 root root    3 Nov 30 12:35 opt drwxr-xr-x  2 root root    3 Apr 12  2016 proc drwx------  2 root root   46 Nov 30 12:38 root drwxr-xr-x  8 root root  115 Nov 30 12:38 run drwxr-xr-x  2 root root 2349 Nov 30 12:38 sbin drwxr-xr-x  2 root root   58 Nov 30 12:39 snap drwxr-xr-x  2 root root    3 Nov 30 12:35 srv drwxr-xr-x  2 root root    3 Feb  5  2016 sys drwxrwxrwt  2 root root    3 Nov 30 12:37 tmp drwxr-xr-x 11 root root  151 Nov 30 12:38 usr drwxr-xr-x 12 root root  172 Nov 30 12:38 var drwxr-xr-x  2 root root    3 Nov 30 12:36 writable   and when I try to do a fuser -m /snap/core/3604 to see who uses the mount, nothing shows up. it reappears every single boot, and I don't know how the heck it's coming up, oh also, there is no sign of it in /etc/fstab. it's also squashfs file system. it looks like it's harmless but I just wanna know why it does what it does. what is it? any help/reply would be appreciated.  Thank you in advance,   MG  ps: I thought this question is different because the loop device is mounted as if it is an primary and working filesystem eventhough it's not busy at all. it gets umounted everytime if you want to, but it shows up again after boot. usually loop devices come up by df -H but for me this loop device comes up even among things that gnome graphical tools show, just like how a hardrive shows in your nautilus.

I deleted the  /usr/share/themes directory, how can I recover it? Is there any way to check if there is any missing file/directory in /Computer directory? This was a bad try to change GIMP and Inkscape themes ("gtkrc" file). I changed all "gtkrc" files that I found in the system (stupid me...) and now my windows and apps are distorted =(

The disk that contains Ubuntu on my computer is 115GB in size.  When the disk was 114.7GBfull.  I started deleting some files here and there to free up around 5GB.  But I noticed the disk was 114GB filled again. I thought it was some cache or swap thingy so didn't give it much thought and went ahead and freed around 40GBby shifting some media files out of the disk.  I have a notification in an hour or so that the disk is full yet again!! 40GB!!! All gone!  So I debugged the problem down to the /var/log/syslog file which was initially definitely less than 20GB. I know this because /var folder was 17GB before I cleared the memory.  /var/log/syslog file is currently 55.9GB!  Could someone be so gracious to explain this anomaly? Is this a bug? Or am I affected with some malware or virus?

I know that most files, when deleted, aren't actually removed from the disk, and can be recovered later.  How can I ensure that a directory I had deleted will actually be removed from the disk? Are there utilities for that?  I'm using Debian Linux.

I'm using Ubuntu 11.04 and I want to free up some space in my root directory, which is overloaded. I especially want to change the path used for installing applications (they are getting installed directly to the root drive).  Another consideration is that I'm working on a MySQL database server. The server is installed in the root directory itself, so I don't want to  risk losing any data.  Please give me some tips to help sort out this problem.

I need to free space on Windows XP SP3.  Q1) What system folders can be safely delete in case I don't need to have restore points etc?  Q2) Can I delete content from C:\WINDOWS\SoftwareDistribution\Download

As the output of df -h shows here, something is eating up 5GB of free space. So, it's not available to use.   I'm also noticing sometimes that the hard disk gets filled up to 100% sometimes. So, I had to restart the machine or delete some unncessary files. Only noticed these in /home partition. Don't know whether these two are related, but appreciate if anyone can put some insight into this.  $ df -h Filesystem            Size  Used Avail Use% Mounted on /dev/sda8             100G   92G  2.7G  98% /home

Please suggest me any particular unnecessary file that I can clean to back everything to normal condition(temporarily). (i.e. any log or archieve or anything ). My var/log has only 40MB and Home directory has 3GB of space(so I believe that's not a problem). Other than that what I can clean up to make space.

I am in the process of cleaning up my system. And I see a lot of space occupied by this folder /var/cache/apt/archives (1.5GB). Is it absolutely necessary to keep all these archives?

My /boot is full. Is there an easy and safe way to resize it? I saw a discussion which said that /boot partition is not required. A /boot directory will be fine. However, I don't think I can have /boot folder while /boot is mounted. Similarly, I can resize /boot because I can't unmount it.  I plan to 1. create a new logical volume, 2. mount it and copy all files from /boot to this new volume, and 3. change mount table to mount new logical volume under /boot.  Since it's /boot, I won't be able to boot if I make mistakes. Could anyone give me instructions?  Steve

Can someone tell me what the .Trash-1000 folder is and how can I remove/delete it?  It taking up 275 gigs of disk space.

I recently wiped my computer to have 14.10 as my only OS. It has 160 GB of storage. That was a month ago. Now, I keep getting prompts that the storage is almost full. And when I look it says I only have 543 MB free. How is this possible? I haven't torrented any large files. I do have Variety to autodownload wallpapers and not erase though.

Is it possible to have 64.5GB log files in Ubuntu? Can I delete those files? My laptop is dual booted and the Ubuntu partition is only 100GB.

After starting Ubuntu, I see the following lines. Should I be worried?  /dev/sda6: recovering journal /dev/sda6: clean, 355773/1835008 files, 470404803/7335680 blocks

I would like to have a list of the installed software on my machine, with the disk space consumed by them alongside. I would prefer to be able to order by largest/smallest, but that is not a necessity.  I am the sort of person who will install software to try it, and never clean up after myself.  As a result, my 7GB (Windows and my Data are on separate partitions, as well as a swap area) Ubuntu 11.04 partition is suffering, and has started regularly showing warning messages.

I want to get a trusted file cleaning tool to remove unwanted files.   When I try to add the Ubuntu Tweak repository it says it is from an untrusted repository.  So, are there any trusted file cleaning tools available for Ubuntu?

We had our samba server (ubuntu 8.04 ltr) share fill up the other day but when I went to look at it I cant see any of the shares have to much on them  we have 5 group shares and then each users has an individual share  one users has 22gigs of stuff a few others have 10-20mb of stuff and everyone else is empty  so maybe like 26gigs total  I deleted a few files yesterday and freed up about 250mb of space today when i checked it it was completely full again and i deleted some older files and freed up about 170mb of stuff but i can watch it slowly creep down in free space.
