anomalous territory

3 pieces of software that I’ve never really seen mentioned anywhere that I simply can not live without:

XnView

Free image browser/organizer with every feature of ACDSee and Adobe Bridge and many more. Just look at the operating systems it runs on: Windows, MacOS X, Linux x86, Linux ppc, FreeBSD x86, OpenBSD x86, NetBSD x86, Solaris sparc, Solaris x86, Irix mips, HP-UX, AIX – that’s dedication right there. I really do use this tool every single day, it’s simply that amazing. The Windows Shell extension alone is wonderful – instant thumbnail on the right-click menu of any supported file type. I don’t know why more people aren’t aware of this tool.

CloneSpy

This brilliant tool lets you find (and automatically delete, if you wish) duplicate files in 2 or more locations on your system. You can do a full byte-for-byte compare, or simply rely on the filenames. You can also designate “pools” so only files listed in say Pool 2 will have the duplicate files deleted, should you wish to maintain any copies found in Pool 1 for example. A truly invaluable tool that’s saved me many, many hours of time and vast quantities of disk space!

RED (Remove Empty Directories)

This tool is fairly similar in function to CloneSpy above, except it works on empty directories and/or empty files. You specify a path for it to scan and it quickly goes through and presents a color-coordinated set of empty directories which it will happily remove with a confirmation click. It’s also smart enough to remove parent directories if after deleting empty sub-directories, said parent is also now entirely empty.
