File fragmentation on disk significantly slows down the file access (read/write) speed, especially in working environments where source code libraries and compilations are frequently updated. So defragmenting software is one of the common tools that computers must use. There are so many defragmenting programs in the market - commercial, free, or open-source. Among them, Diskeeper and PerfectDisk, both with a long development history and solid technologies, are recognized leaders - any other similar applications pale by comparison.

BASIC (Beginner's All-purpose Symbolic Instruction Code) is one of the most popular and widely used programming languages in the history of computing technology. Of course, the only BASIC-based languages still in production today are probably the cross-platform PureBasic and the classic, famous Visual Basic developed by Microsoft.

When I hear a song that I like but don't know its name, I think there are only 3 ways to get its name: 1) try to remember or write down part of the lyrics that I can hear clearly, then search it on the Internet (a bit cumbersome and inefficient); 2) walk over and ask somebody what the song's name is (somewhat inconvenient, and probably even the person playing or listening to this music knows nothing about it; 3) use an app like Shazam on a smartphone to intelligently, automatically, quickly and accurately identify almost any music being played anywhere!

File management is the most frequently used operation in daily computer use, but the functions of Windows built-in File Manager have always been very limited. And, although Windows 7 introduced the concept of Library in order to better organize files scattered across the computer, that wasn't efficient enough. Therefore, many advanced computer users choose to use some third-party File Explorer alternatives, such as Total Commander, Explorer++, FreeCommander, xplorer², Q-Dir, Clover, and so on.
