What can Ultra Compare Professional do for you?

Compare text
Do you work with text files and ever lose your place or forget which is the most current file? Ever wished you could easily compare the differences between file versions?

If you are inspecting your file or code changes by hand you are losing precious time, accuracy and productivity. Compare and merge operations are the cornerstone of a differences tool, and we have placed many merge/post-merge features into UltraCompare so you can easily compare your differences and merge your selections with confidence and trust. Whether you are a lone developer or work as part of a team, how many times have you wanted to compare your text files or compare source code to modified versions, and merge your changes into the newer versions?

System Administration
We all know to make backups - but what happens when something goes wrong and you need to compare your legacy backup with your current backup? Ever needed to compare SQL files between two databases? That's where a compare/merge/sync tool can help.

Remote Files
Do you find yourself needing to compare FTP files? Use UltraCompare's integrated FTP/SFTP to download your text files from the remote server, perform compare/merge operations, then save your files back to the server.
