Free space on SSD disappearing on my M4600

I had about 17GB free, which i never touched as i purposely did not want to fill up my 80gb MSATA ssd. Suddenly yesterday it warned me i only had 40mb of space left. So i deleted some stuff from the desktop, freeing up about 2gb. But now today, less than 24 hours later, its telling me im back 40mb free, and an hour later its telling me i now have 0 bytes free! what the heck is going on?? any help much appreciated!

 

Not knowing what is installed on this drive makes answering tough. Bought mine with Win7-64 installed on the 128GB mSATA and it showed 80GB used as delivered. Bumped RAM to 32GB and it jumped to 101GB after initial updates for Windows and Dell s/w only.

Now I have Windows, Office, Adobe Master CS5.5, Java, 3 levels of Security s/w, and all the other BS everyone has. Currently it shows 67GB used out of 128GB and it is because the Windows installation is optimized. There are a lot of things my IT friend did to achieve this, but the biggies were to kill Hibernation, reduce pagefile to 1GB and move to the 750GB HHD because I have 32GB of RAM. User files were also move there as well; ie Documents, Photos Music, ect. He did something with search and a few other things I do not fully understand, but all is good now.

The big picture was Optimization of Window and using the HDD (very little). This task was beyond me so I can not answer specific questions, but maybe some general ones.

 

do you have the swap file enabled on the SSD drive ?

 

Check out a program called windirstat which will show you how the space is being used in an easy to understand manner.

Also run ccleaner, move the page/hiber files to the hdd.

 

If i remember correctly after upgrading to 8gb ram i set the swap file size to maximum of 1gb...

 

Could Windows have made some restore points?
