Can't find files that fills up laptop disk

Have a HP Laptop running Win7 Pro. Disk is 180GB SSD. The PC is used only for playing different Internet radio stations (with Windows Media Player) all the time.

After running for some months without problems (only restarted after windows updates), the disk is now filled up with "something"....  

Using win explorer shows that one user account is taking 122GB of the space. Browsing though this user's folder shows that the folder C:\Users\username\AppData\Local\Microsoft\Windows has a size of 122GB. Checking files and subfolders in this folder shows no large files or folders. Not sure, however, if there may be some hidden files...

Any ideas what may cause the disk to fill up like this or where the files may be found?

First, show hidden files and folders:  https://support.microsoft.com/en-au/help/14201/windows-show-hidden-files.  You may wish to also un-hide protected operating system files.

You can then use a 3rd party app like TreeSize Free (https://www.jam-software.com/treesize_free/) to get a good overview of where the storage is being consumed.  
It will most likely be a very large cache of Temporary Internet Files.  This is safe to remove if you find this to be the case.

There's a similar question asked on Microsoft Answers.

Hi,

Try running disk clean up which is built in to Windows - it might just solve the problem without doing anything else.

Tree Size (noted above) works well for this issue.

Run Tree Size with Hidden Files enabled and look and see if Windows 7 is creating backups to a schedule. This chews up space.

Using win explorer shows that one user account is taking 122GB of the space

Examine this with Tree Size.  Excessive user Email (multiple large attachments) . How big is the PST file. What is in Documents under Pictures and Videos.

10 Tips to Protect Your Business from Ransomware

big caveat that was not addressed.. run treesize or whatever disk space explorer as an administrator or you will not see everything

Even administrator may not see everything.  Run it as system.  See my article: https://www.experts-exchange.com/articles/28565/Using-Tools-To-Find-What-is-Using-Your-Disk-Space.html

Thanks for the feedback!
Tree Size Free did the job (running as Administrator). Found a very large folder with temp. Internet files (Internet Explorer) and deleted it without problems. Freed up the entire 122GB.

A bit strange (at least in my mind) that IE seems to fill up the disk with a lot of temp files when the PC is only running Windows Media Player and a volume control utility called Volume Concierge. IE is not used, and Chrome is the default browser.

Thanks for all the help!

Hi Olaf,

For those that follow, where were the files that were taking up the space?  I am guessing that Disk Cleanup did not remove them?

Thanks,

Alan.

Disk cleanup didn't remove them.
Files were located in c:\users\username\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5

In this folder there are separate folders for each day and thes folders contains files from each of the Internet radio stations that has been playing during that day. Have attached a screenshot from TreeSize Free to show this.
The files seems to build up continously. Haven't checked if files are deleted if  wmplayer is stopped every day.

are the files caused by 5p non stop hits?  http://oslo.p5.no/player/?channel=2

For that radio station I'm using the following link in wmplayer:  
http://stream.p4.no/p5nonstophits_mp3_mq

In general, for stations under the P4 umbrella, I'm using station links that ends with mp3_mq
For stations in the nrk-area, the links are like

Seems I didn't answer your question directly....
p5 nonstop hits is just one of the stations I'm using. The temp file buildup seems to come from all stations (two are shown in the jpg in a previous comment (above).

then check if they permit to tune down or erase the temp files regularly

Hi Olaf,

I just tested here, and Disk Cleanup definitely clears out Temporary Internet Files.

How did you run it?

If it isn't working, then you may have a much more serious issue with your machine.

Have tried to find a way to limit the size of the temp file, but the most obvious settings don't work.

Alan:
When I worked with this PC I ran Disk Cleanup as Administrator. THinking of it now, I may not have stopped wmplayer when doing this. Current files would probably be open and unable to delete, but older files from previous days should be ok I guess....

Have checked around on different web pages, and I find this problem a few places - none with a good answer. For me, the solution with TreeSize is ok. Have to run updates from time to time, and deleting old temp files could be part of that procedure.

Hi Olaf,

No problem.

For those that follow and find this question at a later date, I suggest not installing software to solve a problem that has a built in solution already - just bad advice in my opinion, that will just create work for consultants (like me!)

Thanks,

Alan.

Did another test...  Stopped the media player.   Ran Disk Cleanup.
The temp files were still there. :-(

Also did another (strange) observation:
Wmplayer is playing different radio stations all day.
The temp. files are created only when playing some stations, while playing other stations doesn't create any temp file.

Links that create temp files:
http://stream.p4.no/p5nonstophits_mp3_mq
http://stream.p4.no/p4_mp3_mq

Link that does not create temp files:
http://lyd.nrk.no/nrk_radio_p3_mp3_m

Strange??
