New Zealand-based MEGA has launched MEGAsync 1.0 FINAL for Windows, the first stable release in a planned trio of desktop tools (Mac and Linux versions are promised soon) giving MEGA account holders access to their cloud-based files via their computers. It follows the launch of the mobile MEGA app for Android and iOS.

MEGA -- which includes Kim Dotcom among its founders -- offers robust, secure cloud storage using 2048-bit RSA encryption. It also offers a generous free 50GB of storage space, with paid-for plans offering up to 4TB secure storage with extended bandwidth (up to 8TB/month).

If you’re working on the PC and would like a little background noise then you could launch your media player, stream something from the web, maybe just turn on the TV. These options could be a little distracting, though, making it more difficult to concentrate on your main tasks.

Atmosphere Lite takes a more effective approach. Much like Sound Valley, which we reviewed last November, it works by generating custom nature-based ambient soundscapes, like a forest stream, a woodland campfire, the ocean’s edge and more. You get the background noise you need, but it doesn’t demand your attention: it’s relaxing, more than distracting.

Imagenator is a portable, open-source tool for converting digital images between various formats: BMP, EXR, GIF, HDR, ICO, J2K, JP2, JPG, PBM/ PGM/ PPM (both RAW and ASCII), PFN, PNG, TGA, TIF, WAP, XPM.

The program supports a range of format-specific options. Export to ICO, say, and you can select an icon resolution from 16×16 to 256×256; JPEGs have Quality and Subsampling options; EXRs give you control over image compression (you can choose lossy, lossless, or none at all), and more.

Most PC users need to work with PDF files, if only occasionally, and there are plenty of free tools around to help. Typically they’ll concentrate on a single function, though; just looking at their names tells you all you need to know about PDF to JPEG Expert and CHM to PDF, for instance.

PDFFill Tools is a little more ambitious, fortunately, cramming 15 functions into a single small and entirely free program. There are tools to create PDFs from images, PostScript files or direct from your scanner, and then you can add watermarks (text or image), headers or footers, merge or split the files, encrypt/ decrypt them, rotate the documents, crop them and more.

3D is everywhere -- at the movies, on TV, games consoles -- but finding PC applications with significant support for 3D images can still be something of a challenge.

If you need to work with 3D pictures, then, the simplest approach is to grab a specialist tool like StereoPhoto Maker. It’s free, compact and portable, and comes packed with options to help you view, create and process 3D files.

VideoLAN’s popular media player VLC for iOS has been upgraded to 2.2 with a revamped iOS 7-style interface, along with new multi-touch gestures for easier navigation.

Google Drive integration and Dropbox streaming should make it much easier to access your media. And if that’s not enough, the new build also adds support for HTTP Live Streaming, m3u streams and https playback.

Piriform has released Recuva 1.5 and Recuva Portable 1.5, new versions of its freeware data recovery tool for Windows PCs.

Version 1.5’s headline feature is its newly acquired ability to recover data from unmounted drives, while it also adds support for the ISO9660 file system as well as Junction Point recovery.

Google has released a brand new version of its experimental Chrome browser with the arrival of Google Chrome Canary 34. The main new highlight in this release is supported for Google Now cards.

Google Now is Google’s card-based service that delivers useful information throughout the day -- it’s available as part of the Google Search app for Android and iOS, and is now being rolled out on the desktop too.

These days, our PCs are shipping with ever increasing amounts of RAM. The idea is that more RAM helps boost performance, but the fact is that if you have 8GB or more of RAM then it’s likely there will be numerous times when that memory isn’t being utilized to the full.

One way to make maximum mileage from systems with larger amounts of memory is with a RAM disk, and the free-for-personal-use SoftPerfect RAM Disk handles the job perfectly.

Video slideshows can be a great way to share a set of photos, and tools like EXESlide make it very easy. Drag, drop, add a soundtrack, export the results, and that’s it: finished.

If you need a little more control over the finished slideshow, though, you might prefer the open source Java-based IMGDissolver. It’s not as straightforward as some of the competition, but the program’s powerful features and extreme configurability mean it could still be worth a look.

EaseUS software has released EaseUS Todo Backup Free 6.5 and EaseUS Todo Backup Workstation 6.5. The new release debuts one major new feature: the ability to back up and restore Android devices to the user’s PC.

Todo Backup combines file- and image-based backup and recovery with disk cloning and -- for paid-for users only -- snapshotting tools.

WiseCleaner software has unveiled Wise Disk Cleaner Free 8.03, a major new update of its Windows disk cleaning and defrag tool. Version 8’s most notable improvement is a revamped user interface that’s less cluttered and easier to follow than previous versions.

Version 8 also adds a new module that ensures all future updates -- which tend to be delivered at least once a month -- are installed automatically, plus promises customized configuration options via a user-created INI file.

If you need to find out more about your PC then you’ll probably turn to a system information tool. That will then access various low-level technical details about your computer, pick out the most important, and try to present them in a readable and accessible way.

Usually this works very well, but sometimes your chosen tool may strip out too much information, or perhaps miss the data you need altogether. And that’s when you might want to turn to RWEverything, a powerful program which doesn’t try to second guess what you might want to know: it just gives you absolutely everything, often in its most raw and basic form.

IObit has launched Smart Defrag 3.0, a major new version of its Windows defragmentation tool, which promises to improve performance by preventing fragmentation of the user’s hard drives.

Version 3.0 comes with a new defrag engine, adds a Defrag & Prioritize Files option for boosting overall performance and revamps the user interface to fit in the Windows 8 look.

Organizing icons on your desktop can be as simple as dragging and dropping them into their new positions. Keeping this new layout is usually more of a challenge, though. Other users of your system can also rearrange the icons at any time, and running an application which changes your screen resolution may cause a similar desktop disaster.

ReIcon is an interesting free tool which offers a straightforward solution. Launch the program and click the Save button to save the current icon layout, or use the Restore option to reload it: easy.
