DiskDigger is a powerful undelete tool that makes it easy to recover lost data.

The program is portable, so there's no installation required - it's very straightforward to use. Just run DiskDigger.exe, choose the drive you'd like to check, and in a couple of clicks the program will be scanning for deleted files.

DiskDigger is surprisingly fast, and very soon you'll have a complete list of everything that the program can recover. If this is a large hard drive then there might be thousands of files on the list, but fortunately you can filter this by file name and size (all jpegs that are at least 100KB, say). The program can display previews of some files, too, so it's usually straightforward to locate the data you need. Then just select your files, click the Restore button and DiskDigger will recover them.

If you find DiskDigger doesn't locate your missing documents, then you can always try a disk scan. This bypasses the file system and directly checks each drive sector, which can take considerably longer but will also recover files that can't be found in any other way. It's usually able to recover documents from drives that have been accidentally formatted, for instance (although this does depend on the formatting tool that was used).

pdfFactory is a straightforward tool that allows you to create PDF files from just about any Windows application.

As with many similar utilities, it works by installing a virtual printer driver. You then open whichever document you'd like to convert, choose the Print option, select the pdfFactory printer, and the program launches to display your file. You may save the document to PDF, or send it as an email attachment in a couple of clicks.

If you need more control, though, there's plenty on offer here. Browse the pdfFactory printer preferences, for instance, and you're able to set the file resolution to anything from 150 to 1,440 dpi, or any custom value somewhere in between. And there are options to set your JPEG compression level, and downsample images to the resolution of your choice.

You can also set details like the PDF file metadata (Title, Author, Subject or Keywords). Security options allow you to encrypt the document, or restrict how it's used (prevent text and images being copied, for instance). You get to choose which fonts may be embedded in the file, and there's an option to convert URLs into clickable links, where you're even able to define exactly how they'll look (colour, border and line style, and so on).

Please note, this trial version of the program will add a watermark to the bottom of every page in the finished PDF file. Once you've purchased a licence for the program and entered its details, this will disappear.

Many people look no further than the humble Notepad app for editing HTML files and programming. While in many respects it can be useful to work with such a basic tool, cutting out unnecessary bloat that slows things down, there is also a strong argument for using something that is a little more feature laden. PilotEdit is an amazing file editing tool that overcomes many of the restrictions of Notepad and adds host of useful features that will help you to work better and faster.

A key advantage of using the app is the fact that it can be used to open huge files – files that are over 50GB in size – and if you are using the app for web site development, there is a built in FTP client that can be used to work with online file over 4GB in size. There is support for dozens of different files types and the program can even be used as a HEX editor complete with unlimited levels of undo and redo.

Multi-line find and replace makes it easy to make changes to code on a large scale, while file and directory comparison and merging means that it is possible to work with the same files on different machines and bring the results together with ease. With the added bonus of customizable syntax and keyword highlighting, PilotEdit is a tool that lends itself to a large number of different tasks.

There is a free Lite version of the program available in addition to a paid for version. There are not a huge number of differences between the two releases, but if you do spend some money on the app you do gain extra features such as the ability to compare, encrypt and decrypt files that are over 4GB as well as the option of working with SFTP for added security. There are other additions such as string extraction and duplicate line removal, but both editions are very capable tools.

McAfee Avert Stinger is a stand-alone portable antivirus tool which can detect and remove some malware.

At its simplest, all you have to do is download the program, launch it, click Scan Now and wait to see what happens. Stinger's straightforward on-demand scanning shouldn't conflict with any other security software, so you can run it alongside your existing antivirus package without any problems. And if the program detects any threats then it'll remove them for you.

Stinger does have a few interesting settings hidden behind the Preferences button. You might want to check the "Boot sectors" box to ensure the program checks for boot sector viruses, for instance. And if you're sure your system is infected, but Stinger can't find anything, then you might try increasing the heuristic sensitivity level. This makes it more likely that the program will spot suspect files, but also increases the chance that it'll highlight entirely innocent programs, so you should also change the "On virus detection" option from "Repair" to "Report only", at least initially.

Please note, Stinger only detects the most common malware specimens (click the List Viruses button to see them all), and offers no real-time protection measures at all, so it's no substitute for a full antivirus package. The program can be useful, though, if you've been infected by a virus which your regular package has missed: Stinger just might be able to find and remove it for you.

Is your e-book collection is a disorganised mess of different formats and competing viewers? It doesn't have to be that way. Calibre is an e-book management tool that will quickly bring order to the situation, and help you get more from the format, and (if you have one) your portable e-book reader.

The process starts by letting the program organise your e-books library. Point calibre at your files and it'll quickly (and almost automatically) build a database around your collection, downloading metadata like covers for extra visual appeal. You can then sort and search your books by title, author, date published, rating, custom tags and more, making it quick and easy to find whatever you need.

Calibre can then display your book, too (as long as it's not DRM-protected), with an integrated viewer that handles all the main formats and supports features like table of contents, CSS, printing, searching, embedded fonts and more.

You also get a comprehensive conversion tool that will convert documents in all the main e-book formats (CBZ, CBR, CBC, EPUB, FB2, HTML, LIT, LRF, MOBI, ODT, PDF, PRC, PDB, PML, RB, RTF, TCR, TXT) to any of twelve standard formats (EPUB, FB2, OEB, LIT, LRF, MOBI, PDB, PML, RB, PDF, TCR, TXT).

And there are many surprising extras. Calibre can automatically fetch news from websites or RSS feeds, for instance, then format the results into an eBook. A powerful sync tool will work with many different devices, from dedicated e-book readers like the Kindle to Android phones and the iPhone. And the program even includes an integrated web server that allows you to access your e-book collection from a browser, anywhere in the world.

Note this is the 64-bit version of calibre.
