C:\ Drive automatically fills up


Recommended Posts

My windows(C:) drive automatically just fills up. I'm just browsing firefox, then suddenly I get this error about low disc space(Less than 200mb free). Then I do a disc cleanup, free some more splace, but still I get this message after a few days.

First I thought Google Desktop's Index was the culprit, but I have moved it to some other drive, still this is happening.

Please try to help...

Load up Windows Explorer.

Right click the Drive C

Select Search

Click on "When was it modified"

Select "Specify dates"

Make sure that "Modified Date" is set with the date set as today for "From" and "To"

Click Search button

It will tell you what is being created - check the filesize, take action.

20 gig work a windows partition isnt very big at all, yourpagefile could be expanding or temp files being kept, go and resize the partition :/

Resizing the partitions seems like a lot of work for something so simple. 20gb is more than enough.

Just try changing the pagefile to the other partition. That will free up a good bit of space to start.

Correct me if I'm wrong (rarely, I am :p) but he said his 20GB C drive was for windows. He didn't say anything about program files. I have windows, my documents and program files on 3 separate partitions. My windows partition is now 20GB, and it's only using 10GB of that. If the OP doesn't have his program files on the same partition, 20GB should be more than enough.

I found a pretty funky free program that'll scan you drive and display in nice pretty coloured blocks how much space each file on the drive is taking up. It's called WinDirStat - it might be worth you scanning your C drive and see what is taking up all the space.

Please tell us how much RAM you have and if you have System Restore on and your Page File set to have Windows Manage it? And let us know if you have Hibernation active in the power settings. :)

I have 1GB ram, Sys Restore is off for all drives (I dont know why) and my Windows Virtual Memory for C drive is 768-1536mb(manual). Hibernation is turned on, though I don't use it at all.

Turn off Hibernation in power management. I would also move the Virtual memory file to another partition or HDD and make the size for largest and smallest the same recomended number (It will tell you what the recomended number is). Also, does anyone else use your computer? If so, they may have turned off System restore. If they didn't then I hope you have not been infected or hacked and would scan for Viruses as-well-as check your firewall settings (making sure it's on). Good luck.

my xp partition is 12 gb and i found that sufficient for windows and programs with much space left over.

only recently i have the need to make it bigger to about 20 gb because of video editing now.

i don't see how you can need a 20 gb+ partition unless you install a whole lot of unnecessary programs. i tend to keep my windows partition lean as i can.

    • Waymo recalls self-driving software after cars enter closed freeway work zones by Paul Hill Waymo, the self-driving car maker owned by Alphabet – the parent company of Google –, has recalled some of its fifth-generation Automated Driving Systems (ADS). It did so after some of its cars drove through closed construction zones. According to the National Highway Traffic Safety Administration (NHTSA), the affected vehicles were capable of driving through a closed freeway construction zone and continuing to drive at speed. The listing on the NHTSA website says that Waymo is currently developing a solution to fix this issue, but in the meantime, freeway driving is being restricted. Waymo will update its ADS software so that vehicles can detect when they can avoid entering construction zones. According to the Safety Recall Report, on April 20, 2026, Waymo’s Field Safety Committee began meetings reviewing an event from April 11, 2026, and five events from April 19, 2026, where Waymo’s autonomous vehicles didn’t recognize and drove past ramp closure signs into the pre-planned freeway construction zones. This took place in Phoenix, Arizona. Separately, on May 18, 2026, seven Waymo vehicles entered freeway lanes with active construction in the San Francisco Bay Area by driving between cones that were placed to show the lane was closed. On the back of both of these events, Waymo restricted freeway driving until it could address the issue. In June, Waymo’s Safety Board reviewed the issue and additional information related to ADS performances around construction zones; then, as a result, it decided to conduct a recall. This development is not good for Waymo as it adds to a growing list of technical hiccups its cars have experienced. Ultimately, it will lead to more scrutiny from lawmakers around the world who will be more cautious about letting autonomous vehicles on their roads without tighter regulation. For readers in areas where Waymo operates, does this news make you more wary about stepping into one of these vehicles?
    • I'm still on Windows 10 22H2 because I didn't want to deal with all the issues in Windows 11, so I waited almost a week before installing the latest Patch Tuesday update (KB5094127), I went ahead and did it, and it was a huge mistake—ever since then, my File Explorer has seen a performance drop of about 30% when transferring large files... Once again, Microsoft has outdone itself! This update cannot be uninstalled, either through the Control Panel (via Settings) or by accessing Advanced Startup Options. The only possible alternative would be to use system restore points, but I’d have to reinstall all app and driver updates (and there’s no guarantee it would work). Or there’s the “nuclear option” of a in-place repair without losing files or apps, but even then, all my customizations would be lost! Microsoft just can’t help but mess everything up! Way to go, Microsoft! But I still don’t want your c****y Windows 11!
