I already noticed this folder on my C: drive and deleted it but here it’s back again. The folder (80.7 Mo) :o is named RD4B335D2AF9F44185AFC417F8D8D4B473DR and it has some files named SavB4E5.tmp or else about 20 Mo! No information in the details. I was running WD at the time of their creation friday night and it may well belong to it. Otherwise it’s malware creation. WD folder is on my D:/ drive, may be it explains something too. Do I have to upload the file to ALWIL? ???
Hi gdiloren,
Did you analyze the file with FileAlyzer? What kind of file is it? There you may have a clue where it came from (music, banking SAV?). FileAlyzer can be had here: http://www.safer-networking.org/files/filealyz.exe

FleAlyzer, an application to analyze the contents of files and view them.
For advanced users. Right click your mouse on the file to analyze, and then choose Open into FileAlyzer.

Put this tool onto your anti-malware pendrive as well, my good friend, it can come in handy some time, together with RunAlyzer and RegAlyzer (downloads at the download-site of Spybot S&D).

P.S. You can also use this shareware (as long as you deem useful) : http://www2.neweb.ne.jp/wd/morimoto/en/ArcDiff/
Hi Polonus,
I downloaded FileAlyser and it does not say much. I think I’m going to remove the folder with RevoUninstaller. FileAlyser asked through Comodo 3 's Defense + to access the keyboard, I press allow, did I do rigth? Here are some screen shots of the filealyzer results:
I deleted the file containing these huge temp files and WD doesn’t show any change. May be it’s related to Auslogic registry defragmenter’s analysis. Let’s hope so. :o
Hi gdiloren,
Who will miss all that zero’s…?

Just happened to browse unlogged and noticed my attachments aren’t showing. I guess it shows only to those logged in??? If I log in the thread is complete with attachments! 
From what I can tell, this may be a left-over folder from Microsoft Updates, Go to the last post here:

Thanks Mark,
That’s exactly that folder. I’m more inclined to say it’s an Auslogic Registry Defragmentor’s affair but it can well be a Windows Update (updated WD motor.dll). Impressed with your web search skills as I did a web search of the folder on Google and it couldn’t find anything!
I just used Auslogic Registry Defragmentor. After reboot, the folder appeared and it can safely be deleted. Somebody should contact the software authors about that. ;D
I just contacted the support at Auslogic. Hope this “bug” will be solved soon! 
I have Auslogic Registry Defragmentor installed but never saw the weird folder… it’s not there. ???
That’s weird, are you on Vista??? ??? It’s there after having defragmented
I’ve used it, maybe it is created and then deleted… Yes, I’m on Vista.
Did you boot after defragmenting?
It is forced to boot after defragmenting, a boot is necessary!
I’ll run and boot…
Technically you shouldn’t need to reboot after a defrag, none of my defrag tools require it.
I’m sorry David, but that’s all what’s about Auslogic’s Defragmentor, it just warns you it has to reboot to defragment. Once rebooted you’re defragmented! ;D
