Bibliomania doesn’t get better than this! Read on as I walk you through this cool utility. We all hoard data in one way or another. Some of us have loads of music and some of us have loads of movies. It all began when personal computing became affordable and all of us got to play with these virtual packets of data called files. Then came the Internet and the Napster era — MP3 files flowed in the thousands. That called for some serious media file management — what we now so effortlessly do (most of the time) using Rhythmbox, Amarok or iTunes (if you’re an Apple fan).

One way to get your feet wet is with Cygwin, a free program that provides you with a Unix-like command line, without having to leave Windows. Cygwin is not a Unix emulator (it cannot run native Unix programs, although it does contain the tools needed to compile and run a program from source code), but it does have a wide array of optional packages that let you use most of the tools and utilities that you would commonly use in Unix, in Windows.
