When you access a website, the computer will perform DNS caching, which means that the data in the form of domain name and IP address of the website that you access are locally stored in the computer for a period of time, so when you open a web page that has previously been opened it will feel faster because the computer has remembered the IP address and it does not need to contact the DNS server. However, which often be a problem is that the DNS cache can sometimes be corrupted and it causes problems like some websites that can not be accessed when the internet connection has no problem. At this point the DNS flush is needed.
DNS flush will force the computer to clear the DNS cache or in other words it forces the computer to erase all memory of the domain name and the IP address associated with the domain name. Once the DNS cache is empty, the computer will start asking for new data from the DNS server and it will build DNS cache from the beginning.
Windows 8 as the latest operating system from Microsoft does have nice interface, effectiveness and better security. However, sometimes we still use the old software that is made in the period of Windows XP and that is not updated by the author.
Indeed, there is a feature “Compatibility Mode” in Windows 8, but this feature is not perfect. There are some older programs that really have to be run in Windows XP.
Windows XP in Windows 8
Dual boot? That’s what you definitely think right now. This dual boot system (Windows XP & Windows 8) on your computer will solve this problem. You can run your old programs in Windows XP and when you will just surf or do other works, you can use Windows 8. But of course this will make the time wasted due to the process of switching between Windows 8 and Windows XP and vice versa that requires a fairly long time. There’s another deficiency in dual boot system. You need a license for Windows XP. Isn’t that bothering?
Sometimes we need to create a list of files contained in a folder or drive, but there is no menu in Windows (XP/Vista/7/8) to do this. If you search about how to do this on the internet, you will find many article and tutorial about it, but they did it through command prompt. It was quite a hassle because you have to repeatedly typing the command manually. This time we will create a simple batch (.bat) application that can generate a text file contains list of files and sub-folders from the folder where this little application is located, and if you want create a list of files in another folder, just move this app into that folder.
Open Notepad and then type this:
dir /b > fileslist.txt
if you want a recursive listing, type this:
dir /b /s > fileslist.txt
