What is eating up my hard disk space when I don’t download anything or installing any new programs? Well, a folder in Windows called Winsxs could be the source of the problem. The Winsxs folder stores multiple copies of drivers in order to make multiple programs run without any compatibility problems. My own Winsxs folder is 10GB and it’s the largest folder in Windows, and it grows over time. When I look inside the folder, it seems like many of the dll files are duplicates, but they are different versions of the same file. The reason for that is that different programs use different versions to be able to run properly.
Having a large Winsxs folder is usually no problem, but if you have a laptop or an old computer with a small hard disk, then it could become a serious problem. It seems like the Winsxs folder is an unnecessary part of Windows, that just use the storage space. But don’t ever try to delete files inside the Winsxs folder because it could stop programs to start or even break Windows. You can try to clean up the Winsxs folder by using tools inside Windows 7 and Vista.
How To Cleanup The Winsxs Folder In Windows 7 And Vista?
1. To cleanup the Winsxs folder in Windows Vista SP1, click Start and type in “vsp1cln.exe” in the “Run” box and hit enter. A new command prompt window will appear, press “J” and the cleanup process will start.
2. To cleanup the Winsxs folder in Windows Vista SP2, click Start and type in “compcln.exe” in the “Run” box and hit enter. A new command prompt window will appear, press “J” and the cleanup process will start. This method is not bulletproof but it could help you reduce the size of the Winsxs folder.
3. To cleanup the Winsxs folder in Windows 7 SP1, open up the Command prompt as an administrator and type in: DISM /online /Cleanup-Image /SpSuperseded and hit enter. This method helped me reduce my Winsxs folder from 10 to 8.5GB but other people have had more success when using this method, and reduced their Winsxs folders with up to 50%.
How to reduce The System Volume Information folder size?
A great little tool that can help you to see how much space each folder use is Treesize, the free version is enough. The System Volume Information folder could take up a lot of storage space but it’s pretty easy to reduce it. Open up the built-in Disk cleanup tool in Windows and choose the (C:) or where your Windows operating system is located and hit ok. Click on the “Clean up system files” button and choose (C:) again. Click on the “More Options” tab and under: System Restore and Shadow Copies, hit the “Clean up” button. This will remove all old backup images and restore points except the most recent backups and restore points.
These two methods will help you to get more storage space, but if you have a very small hard disk, it would be a good idea to upgrade to a hard disk with more space. The Winsxs and System Volume Information folders use a lot of space but it’s actually necessary for your operating system to be able to run. Don’t ever delete files inside these folders manually, don’t break your Windows.
