M$ Windows is eating your hard driver

发表于 2008, October 24

No matter Bill says how friendly M$ Windows is. It is eating more and more my free disk space. Toady I figured out some tips for releasing disk space. In Windows file explore, you can not see the folder size without checking on property. So you may need a tool, something like FolderSizes. FolderSize helps me to know more about my heard diver. It shows me there is a folder ‘System Volume information”, this folder is 6.20GB big. What the hell is that??? I can not even see it in file explore. Then I check on Folder Options, here are so many hiding options for you. In order to take out that big folder, I unchecked ‘“Hide protected operating system files and folders”, then the folder shows up. But I can not open it sine I really wants to know what hell is been hidden in that folder. A error message box popup up"Assess is denied.” WOW this is my laptop, I am not able to access the folder. Is this a M$ asset? In FolderSize, I can go inside this folder; it has so many files. Everything in this folder looks like patch file. I have no idea where and when it went down my computer; or this dame OS made it. Now I’m deleting these files and folders in folder ‘System Volume information” from FolderSize. Another error message box popup up; it says “Cannot delete XXX000.ps1: It is being used by another person or program”. Kidding me? Does anyone share this laptop with me at this moment? Fortunately I have openSuSe, I issued rm -rf command after booted into openSuse. Now 6.2GB space was released.

Xen quick start guide on openSuSE Linux 10.3

发表于 2008, August 27

If you had installed VMWare workstation on any Linux, you may have kernel source problem. Because a default Linux installation do not include kernel source package. I’m just saying that you should always play with open source Virtualization, Xen or Virtial Box are all good stuff to run ;)  . I got some screen-shots for you if you don’t have idea how do install Xen. The true is Xen is faster then VMWare on my laptop. I would not work with VMWare anymore.My laptop is a DELL D630 with openSuSE Linux 10.3 and XP (just for work).**1) Install Xen packages via yast from DVD.**
