The webσελίδα Diffnow offers free and online comparison between two files, texts or urls.
Imagine having two large files you want to compare. It can be, for example, member lists from a club from two different years or two versions of a text document. And you want to find the differences easily and quickly and of course free of charge.
If the files are small, it may be simple enough to do by hand, but when they are large the task seems rather daunting. There are a ton of file comparison tools out there in the electronics world computers που μπορούν να κάνουν τη δουλειά για σας. Συνήθως ονομάζονται προγράμματα "diff" και ενσωματώνονται πραγματικά στα Windows and Mac OS. On a Mac all you have to do is open a terminal window and type: diff file-1 file-2 (where file-1 and file-2 are the files you want to compare).
On a Windows computer you should open a command window and do the same, but replace the diff command with the FC command (which stands for File Compare): fc file-1 file-2
Before you get excited, we have to tell you that the results from these built-in command line tools are not easy to read.
Fortunately, there are many available review tools available on the internet, which are also free and easy to use, and produce results that are much more comprehensible.
One of them is DiffNow which can compare not only Office documents (doc, docx, xls, xlsx, ppt, pptx) but also PDF, HTML, plain text and many other file formats.
