■ xplorer² v4.2 released with artificial intelligence for photo cleanup

You find artificial intelligence popping up everywhere nowadays, so why not in a file manager too? Using machine learning algorithms, xplorer² teached itself to recognize bad quality photos (blurred, shaken, too bright or dark etc). It also learned to recognize pictures that are very similar to each other (albeit not exactly duplicate). Using these 2 new tools you can examine your old photo collection and quickly find those that are not worth keeping — and delete them to free up your disk space.

There will be a separate blog article explaining the new AI-driven photo cleanup tools, but quickly I can mention that to detect blur you use the new file attribute Blur available through <Alt+K> (Select columns menu command). For JPG photos it will show a number, which is over 100 for bad quality pictures (probabilistically). To detect similar pictures, first you put all your JPG files in a scrap container, then use Tools > Find similar photos menu command and they will be grouped by similarity. Then you can choose which ones you don't need and remove them. The command is similar to the duplicate files checker, but as you can see it detects pictures that are slight variations of a scene too!

Upgrade information

Version 4.2 is a free upgrade for most people that already own v4.x licenses. A small exception is people who got a v4.0 key as a free upgrade using the "free upgrades for a year" policy. So if your unlock key is dated before 1 February 2018 (check your About dialog), then you'd need a new key, but you may be able to get one with a discount. On the other hand if you've already bought a v4.x key or you own the free lifetime upgrades cover, you don't have to pay again.

Please use Help > Check for updates menu command or the equivalent from ribbon's File leftmost tab to get the new version. If you don't have xplorer² installed try the download page for your free trial.
