Folders under /system with nusb3co.dll.mui

[gabriolinari]

hi guys,

I just came across my system32 folder and noticed something odd, there's a handful of folders, 30 to be exact (see screencap) with this file inside nusb3co.dll.mui

I think it had to do to a SFC scan. I launched some time ago, but I couldn't be sure, they all have the same date...

any thoughts?

thanks

dll vs dll.mui

Well here's some info:

Some system files/locations are new to Windows 7 and were not present in earlier Windows versions, like XP. If you want to change look of other menus, dialog boxes like RUN, Progress, System Properties, Start menu, Taskbar Properties, etc, you'll have to edit some other system files which you needed to edit in Windows XP. But there is a little difference, now those files don't contain the resources but their .MUI files do.

For example in Windows XP, RUN dialog box resources were present in "%windir%\System32\Shell32.dll" file but in Windows 7, the resources are present in "%windir%\System32\en-US\Shell32.dll.mui" file.

All these .MUI files are present in any of following 2 locations:

%windir%\en-US\
%windir%\System32\en-US\

So in answer to your question if you find a nusb3co.dll in your system32 folder (or anywhere else) then you shouldn't delete the corresponding nusb3co.dll.mui file.

I would leave them alone. Unless you really understand what you are doing the entire contents of the windows folder should be considered off limits. As the files appear to be only 1 K in size what do you hope to gain?

ok thanks but why there's so many dupes??? see attachment

they all have the same file inside : nusb3co.dll.mui

also, I just searched c:\windows for nusb3co.dll and I have just one, in

C:\Windows\System32\DriverStore\FileRepository\nusb3xhc.inf_amd64_neutral_0bef1a22bb2463ef

any more clues???

thanks

well is just for the sake of keeping things clean, windows has a tendency to clog things up!

They're probably language files that are in region specific folders.

The dll is associated with the Renesas Electronics USB 3.0 Host Controller Driver

Driver?

Well it looks like a driver that's installed by the manufacturer so I'd leave it alone.

Read down to the bottom of this page:

Renesas Electronics USB 3.0 Host Controller Driver - Should I Remove It?

As for why there are many folders - I haven't got a clue. Maybe someone who has the same driver installed can confirm that it's normal?

I'd think that it's wise to heed Slartybart's advice.

Responsible and knowledgeable members of any forum are going to be reluctant to advise that a file or folder is unneeded and can be safely deleted. This is particularly difficult on a system they have no access to and have only limited information regarding. All modern operating systems are very complex, a great deal of which has never been publicly documented. To further complicate matters there are third party drivers and applications to deal with, for which documentation is limited at best and often non-existent. Experience is of limited value in this regard because it can become invalid by a minor change in the OS, application or driver.

No one can be 100% certain that a specific folder or file on your system is safe to delete. The only safe thing to do is advise that it be left alone. That has been done. I can understand the desire that many people have to keep things neat and tidy by deleting unneeded files and folders. Doing that with your personal files is one thing. But for system files and folders that just isn't practical.

I went ahead and deleted all those weird folders with the .mui file in it, they are in the bin right now as a precaution, system works fine, no yellow signs in the device manager on Renesas Electronics USB 3.0 Host Controller Driver.

thanks all
