Hi Xephion,

Winsxs is known as "Windows Side by Side" Its used as the compatibility store for windows DLLs and allows windows to run programs built for previous versions of its operating systems...

Gparted is a good open-source and free partition manager ;)

Hi Xephion,


Gparted can format & partition Microsoft Windows NTFS Volumes, It uses a Linux-base for creating a LiveCD Graphical User Interface for managing partitions for many different Operating Systems including Linux/Windows 98/2000/XP/Vista ;)

think its worth me posting this for future users who wish to learn a little more about winsxs and how it works

The Secret Of Vista's Winsxs Folder.​
Most of you may have noticed the WinSxS folder and been surprised at its size. For those who have not, the folder is situated at C:\Windows\Winsxs and has a whopping size ! Mine is almost 5 GB and has around 6000 folders & 25000 files and occupies almost 40% of the Windows folder ! While the size of this Winsxs folder, in XP is around 25-50 MB; its large size in Vista, is intriguing, to many ! Check the image below.​




  • So what is the mystery of this Winsxs folder in Vista?
  • What's the purpose of so many folders & sub folders?
  • What does it contain?
  • Can you delete this directory?
  • Can you atleast move it somewhere else?
  • Or can its size be reduced to save disk-space?
The Winsxs folder, stores multiple copies of dll's in order to let multiple applications run in Windows without any compatibility problem. If you browse inside, you will see what look like a lot of duplicate dlls, each having the same name. These are actually, different versions of the same files which are being stored; as different programs may require different versions. In short, Winsxs, which stands for 'Windows Side By Side', is Vista's native assembly cache. Libraries which are being by multiple applications are stored there. This feature was first introduced, in Windows ME and was considered as Microsoft's solution to the so-called 'dll hell' issues that plagued Windows 9x.


In Winsxs the 'backup' folder is the largest as can be noticed in the image below.



Again, as can be seen in the image below, in the Winsxs folder, the 'Other' File types takes the bulk of the space. These primarily consist of .imd, .ngr, .csd, .dll, .dll.mui, .exe and such other file types.



In Vista, there isn't a 'dllcache' folder and nor can you find the 'i386' folder, where the system caches (like in XP) all it's source modules. It is this WinSxS folder which stores the shared components of side-by-side applications. These files can be multiple versions of the same assembly or application. Every side-by-side assembly has a unique identity. One of the attributes of the assembly identity is its version. "Side-by-side assemblies are used by the operating system as fundamental units of naming, binding, versioning, deployment, and configuration. The Winsxs folder includes all manifests, optional components and 3rd party Win32 files".

But, why so many subfolders, and why keep so many different versions of the same dll, exe or other files ?

As mentioned, Windows stores the old dll's and library components in the WinSxS folder. Now if a newer version of this file is a part of the OS, but a particular application requires a particular older version for running, then the older version from the winsxs folder will be used, leaving the newer version in its present place, for other applications which may require it.
So obviously you cannot delete this directory or move it elsewhere. Nor is it advisable to delete anything here, as such a step could probably make your applications un-workable or even break your system! If you have many applications installed, you can expect to have a jumbo sized winsxs folder.
If you delete components from the WinSxS folder like the manifets or the assemblies, etc, you could be in trouble. Each system would react differently. What may work for one could break another! For instance, if you install a program that requires that particular assembly, which you may have deleted, then that program will just not run! Compressing the folder is also a no-no, as it could cause problems during WindowsUpdates or while installing a Hotfix. The safest way to clean it, is by simply uninstalling applications which you don't require. However, this too is not fool proof, as many applications still leave behind their files here, since they may be shared between other applications. So the probability of dud unused dll's being left behind is quite high.
And if you are into trying out new software or installing and uninstalling frequently, you may notice that your winsxs size is indeed large, as Vista will store multiple copies of these dll files, in order to let multiple applications without compatibility problem.

Is there or Has there been any usable advise on reducing the size of the WinSxS folder?

My WinSxS folder is just over 6.5gb and growing..
Un-installing programs doesn't help much...

Any answers would be greatly appreciated.

ok then....:sick:

Now it's just over 9gb size.
And no way of managing the size.
And we wonder why people say vista is bloated.

ps no new software added.

Vista is less bloated than OSX :sick:

A 500GB HardDrive is $100 so I dont know why you care about 9gb of space used by WinSxS :sarc:
I try to make my C:/ partition as small as possible.
C:/ is just for operating system and essentials....
No programs load to C:/
Run computer as standard user mode, only admin use is "run as administrator".

When an application runs it still has to go thought all the links to find the link it needs.......
and MS still doesn't seem to remove redundant links.

Don't know about OSX, but if it's Linux based it should be able to be cut down to only the drivers that are required.

I just want to control/configure my own pc, for the use, I have for it.

But the spooky thing is,
I still quite like Vista X64
