zsCompare

From Zizasoft:

zsCompare, the award winning file comparison utility from Zizasoft, allows you to manually or automatically compare and synchronize Windows or Mac OS X files, folders, zip files, and jar files between local directories or networked computers.

You can also compare the contents of text files line by line, and then merge the files to include only the changes you want. You can also compare text that has been input either by typing it in, or by copying from non-text files such as Word documents, Excel spreadsheets, and PDF files. Finally, zsCompare includes the functionality found in zsDuplicateHunter for free. This functionality allows you to find and remove duplicate files from your computer which saves hard drive space and makes common operations like searches and backups faster.

Pricing for zsCompare starts at $35 for a single license with discounts available for multiple licenses.
