zsCompare allows you to manually or automatically compare and synchronize 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. 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, it 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.
