AT&T developed a graphical image format in 1996 called DjVu, and implemented the .djvu file extension for its data output. DjVu uses image layers and a three-tiered compression scheme to make high quality graphic images. Because these images are so small, they are ideal for web site implementation. The .djvu file format is a free and open one, but AT&T maintained the rights to commercial development of application software. Since the creation of the DjVu format, ownership of the commercial rights has been transfered several times, with LizardTech being the current owner. The full line of LizardTech software still supports the .djvu file format including their Express Suite, GeoExpress, Express Server, and Spatial Express packages.

I really do love FileCure because it's so easy to use - you don't have to be some kind of computer guru to get just what you need!

Plug and play? Not even close. I spent a lot of time trying to get my new, so-called 'plug and play' scanner to work. I was about ready to take it back. ParetoLogic FileCure got it working and saved me a needless trip (and gas!!) back to the store.

I have to admit I'm no computer geek. When something goes wrong, I usually have to call someone to fix it and it costs me a lot of money. When my printer wouldn't work, a friend of mine suggested I try ParetoLogic FileCure a try. I figured it was worth a shot because I was going to have to pay for a geek anyway. I was so happy when it worked... and worked properly!

I figured the graphics card my grandson gave me was broken when I couldn't get it work on my computer. It turns out that I just didn't have the right driver. ParetoLogic FileCure got it workin.

Hello FileCure folks:
I can't thank you enough for this great product. I just bought a new Vista machine and had been having all kinds of problems. First it was my screen and once I got that fixed it was the printer . Finally, my son suggested I try your product. It worked great and continues to keep my computer working. Thanks you.

I hate paying a lot of money for anything. That's why I buy mostly used computer equipment. Last week I thought I got taken when I bought a scanner. It just would not work. ParetoLogic Driver Cure got it working. With the updates, it makes sure my stuff will keep working and that I don't have to pay more money.

I work at a school so my mom thinks I am some kind of computer whiz. I have wasted so much time trying to get her stuff to work. Our IT guy suggested I try ParetoLogic FileCure. It has been a godsend and has saved me a lot of wasted hours. My mom and I can't thank you enough.

My wife bought me a new Vista system, and ever since I have had problems with some of my hardware. I saw FileCure, and decided to give it a shot. Ever since, the Vista and my hardware have been working great. Thanks!

I upgraded my system to Vista, and my printer started to act funny. No error messages, but it just wasn't working quite right. I read that drivers could sometimes be the problem. I looked online and saw FileCure. After downloading FileCure, my printer works great. You guys rock!

The original authors of DjVu have capitalized on the format being free and developed their own software called DjVuLibre. It is an open source implementation of the DjVu technology which is licensed under the GPL license. DjVuLibre has full support of the .djvu file format and includes features such as a viewer, browser plug-ins for Mozilla, Firefox, Konqueror, Netscape, Galeon, and Opera, and tools for decoding and encoding. It can be downloaded free of charge from the DjVuLibre website. The site also has links for the necessary plug-ins.

There are two moderate drawbacks to the DjVu format, the first being its limited use. Because web developers have not broken away from the standard .jpeg and .gif on a large scale, most browsers don't have the DjVu plug-ins installed by default. Web users may open a page with DjVu images and notice they are not displayed. Instead there will be a place holder for the image and the user will have to download the plug-in. The second drawback is the compression technology. The DjVu format uses lossy compression rather than lossless compression. With lossy compression you still get a good compression rate, often with a smaller image than .pdf or .jpeg, but when decompressing some resolution is lost. For most users the loss is barely noticeable, and DjVu is quickly becoming a favorite format for digital books, manuals, and journals.
Several programs are available for viewing DjVu images, some with extra features such as printing, exporting, text copying, and bookmarks. WinDjView and it's cousin MacDjView are two examples of this type of software. Both programs are free downloads and have a long list of great features. Other readers that support DjVu include eSnips DjVu Reader and Handy Djvu. With DjVu Reader & Converter it's possible to not only open a view DjVu files, but also convert them to eight different formats including .pdf. Universal Document Converter is another software application that allows DjVu conversion.
Users who have already created complete documents and want them converted to DjVu can do so through a free web-based service called Any2Djvu Server. This is a public service offered by DjVu Zone. With his service users can either upload documents and images to the server and Any2DjVu will handle the conversion. Alternately, the user can provide a URL link to their documents and files, provided they reside on a server with open access.
Errors occasionally occur with both DjVu browser plug-ins and DjVu readers. There have been numerous reports of bad plug-ins downloaded from various independent websites. It's recommended that users install their browser plug-ins using the links on the DjVuLibre or LizardTech Websites. Errors related to the viewer and converter software are normally connected to a corrupt or missing djvu.dll file. If a user knows for sure the file is missing, a new one can be downloaded and installed. If it has been corrupted, other files might be as well, so a complete uninstall and re-install are suggested.
