DeltaCopy - Rsync for Windows

"In general terms, DeltaCopy is an open source, fast incremental backup program. Let's say you have to backup one file that is 500 MB every night. A normal file copy would copy the entire file even if a few bytes have changed. DeltaCopy, on the other hand, would only copy the part of file that has actually been modified. This reduces the data transfer to just a small fraction of 500 MB saving time and network bandwidth.

In technical terms, DeltaCopy is a "Windows Friendly" wrapper around the Rsync program, currently maintained by Wayne Davison. "rsync" is primarily designed for Unix/Linux/BSD systems. Although ports are available for Windows, they typically require downloading Cygwin libraries and manual configuration."

I initially found this program while reading an article on using FreeNAS to back up windows machines: http://www.dailycupoftech.com/windows-backup-with-rsync-and-freenas/

PDF-T-Maker

"You create documents in Microsoft Word, spare no effort to produce proper headings, lists of contents, links and cross references, an index, and want to pass on the document as PDF file? You want to produce rich PDF files which contain all meta information from your Word document as bookmarks, hyperlinks, comments etc.? You look for a solution that costs little or even nothing?

Your solution could be PDF-T-Maker: PDF-T-Maker is an add-in to Word. Similar to almost any PDF converter, as first step PDF-T-Maker converts your Word document into a PostScript file. You can send this PostScript file through a distiller, that generates the PDF file from it. As distiller you may use stand-alone solutions such as Adobe Distiller or GhostScript as well as pre-configured, highly automated solutions such as FreePDF XP, qvPDF, PDFCreator etc. This way, with a minimum of effort you can configure a one-click solution that does not cost a penny."

Works with PDFCreator, apparently. I found the following comment in the release notes for PDFCreator v 0.9.5:

"No hyperlinks possible (Hyperlinks for MS Word are possible with the combination of PDF-T-Maker and PDFCreator."

Free WinUnRAR

"Free WinUnRAR is a little and easy to use utility. If you have it installed, you are able to decompress '.RAR' files in a fast and simple way (shell context menu - right click on file)."

Works great. A nice alternative to commercial products such as WinRAR when all you need to do is decompress the occasional RAR compressed file.
