Drive C on Windows 7 Pro pc low on free space

Running Windows 7 Pro on a Dell Optiplex 9600.  It's part of a small office peer-to-peer network.


Drive C is running out of room.  It is a SATA drive installed inside the pc.  I have run Cclenr tool, it deletes some files but the free disk space on drive C keeps gradually getting smaller.  There must be some logs or other files which could be deleted.  For example, backups are written to a usb drive.  What old backup logs might be lurking around if any?

What steps would you take to determine what files could be deleted and gain disk space?
I am not a computer expert.  I hope you will write detailed steps to find and remove files.

Thank you for your help.

First, get Tree Size (Jam Software). Install it and run it. Look at the sort on the left side to see the biggest folders / files and the details on the right side to narrow it down.

Look in c:\users\username\appdata\local\temp and delete what you can in here.
Look in c:\windows\temp and delete what you can in here.

Now run Disk Cleanup (admin tools) and make sure you select Recycle Bin and Temporary files.

Do this and that gets rid of junk and will reduce your overall disk usage somewhat.

Next: Check if backups are running (Windows or Vendor). These things chew up disk space and only keep the most recent backup

Finally:  carve off older documents and store them somewhere else.

I do NOT use or recommend third party cleaning tools. Use Windows - it knows what it is doing.

Delete your old system restore points and also use disk defragment to group your files together. Another thing to do is delete the hibernation files.

In a machine with 4 GB of memory, the hibernation file may not be the major source of your disk usage. It is not on my machines.

You did not tell us what the actual size of C drive is. It is normL that C drive gets filled up during updates or vss snapshots (backups) but we need to know how much does it get used.

what i do to gain space, is the following :
-open add/remove programs in control panel, and uninstall all toolbars, + old, or not needed software
-move data to another drive (external or internal) - in most cases, pictures and videos can take up a lot of space -  you may do a search for *.jpg or *.mp3
-open disk manager, and check if there are partitions with free space left

***install a 2nd drive for copying the data is often very useful - also you my redirect my documents to it to gain space on drive #1

Besides running the cleanup tool thinkpads mentioned, also delete the contents of c:\windows\SoftwareDistribution\Downloads.

Backuplogs depend on what tool you used for backing up, so check with your tool...

Besides that, do you have a separate data partition, or is everything on c:\?

Make sure that in your system settings the size of your dump files is set to make minidumps, and not large dumps. Otherwise any BSOD event will create a huge dump file which takes up a lot of space.

also -  inspect your downloads folder, and delete what you don't need anymore
this goes also for mails, and data in my documents (often you have even more than 1 copy of the same)

The amount of time you invest in cleaning up your hard drive it would probably better to invest in a larger hard drive.... As your time is valuable or worth money.

The files you posted don't provide adequate details on disk usage.

Get a copy of Tree Size as I suggested above and find out specifically what it taking the space.

since your C drive is a 160 Gb drive - can it be it is an SSD drive?
also - what is the reader partition used for?

amlso -post a screenshot of the C: disk expanded, so we see the folders

did you delete something yet? or uninstall programs?

Since you have several disks, you can uninstall software and install it to another disk. You can also make sure that the main pagefile isn't on C, but rather on another disk. Only leave a 256MB pagefile on C so that minidumps can be made.

Restore points are removed by right clicking on "Computer", selecting "Properties", "System Protection", "Configure", then selecting the disk and clicking on "Delete". You can also adjust the size of your system protection and create a new restore point there.

But first I suggest you do what thinkpads and I suggested in our first comments (disk cleanup wizard, delete contents of c:\windows\SoftwareDistribution\Downloads).
