I had previously posted both on software developers’ sites (Nirsoft, Sysinternals) and software portals (FileHippo). I can say they have one thing in common - you may find what you seek there but you may fail as well.
Softpedia is software portal that is different in one way. Softpedia has everything for everyone. It has entries on hundreds of thousands of software titles. Software for all platforms (from desktop to handheld). Not limited to stand-alone software but including plugins, extensions and even widgets.
What I personally like most (aside from value of such massive collection in one place) is plenty of unbiased editorial reviews on popular software and that portal cares to host old software no longer available from developers.
