windows - How to find which program is writing to the C: drive?

I have a problem. The system regularly runs out of space on the C:/ drive. Is there a simple way to take a snapshot of the disk space usage, so that I could free up some space, take this snapshot, wait until the drive fills up again and compare (and then use e.g. Process Monitor to find the responsible program)?

Or find the program writing a lot to C: directly?

Answer

You did not specify which windows version you are using, but if it is not ancient (e.g. not XP or older) then the easiest way to do this with build in software would be:

1. Start the task manager (e.g. press ControlAltDel and click on "start task manager").


2. Go to the performance tab.


3. Click on "resource monitor".


4. Once the resource monitor has started, go to the [Disk] tab. It will list current program and how much they read and write to the volumes.
