As is the case so often with programmers or writers, there are probably several versions of the documents we use. One merit to having several versions of your documents is that it gives room for you to merge differences and monitor changes between them after comparing.

Furthermore, copying files may occasionally result in data loss, necessitating comparisons to verify nothing has been damaged.

With edit source code editors, Microsoft Office applications, and even across two file directories, comparing files is possible. In the Mac, Windows, and Linux operating systems, you can usually compare files in several ways.

I will be showing you how to compare files and would be starting with my favoring notepad++

Guide on Comparing Files in Two Folder

We have so far learned how to compare files in Notepad++ and in Visual Studio Code, now let us discuss comparing files in two folders.

You may need to compare the contents of two directories and even subfolders, not simply two files, for certain tasks. Manually doing so would be very time-consuming and laborious.

There are, fortunately, shortcuts available. If you’re a Windows user, the WinMerge utility program is probably your best bet. This is a completely safe and free program that you may use as follows:

So just like I said when we used Notepad++, the first step also would be to download the Winmerge application. It is free and open-source.

Use the keyboard shortcut CTRL + O when the installation is complete. The folder comparison box will open as a result of this.

The process of comparing begins right away. If the folder sizes aren’t too large you would not need a long waiting period. If the directories you’re comparing are big, though, you’ll need to be patient.

WinMerge will show files that are unique in white and files that are not comparable in yellow. Overlapping files will be labeled in grey. By right-clicking on the files, you can see the differences.

The Terminal may be used to compare two directories on a Mac. Developers use it as a command-line utility tool to perform fast and simple modifications to the operating system.

Guide on Comparing 2 Word Files

If you write on a regular basis, comparing past and present Word document versions of text files may be very useful.

To compare two editions of a document in Word, follow these steps:

In Word, open any edition of the doc and go to the “Compare” ribbon under the “Review” tab.

You may also use the “Combine” option from the “Compare” ribbon. It enables users to merge several writers’ updated Word documents.

Guide on Comparing Two Excel Files

When working with a small dataset, analyzing Excel files may be useful. You may use the built-in comparison tool to manually examine the files.

Consider the following scenario: you have two Excel files recording inventories from two separate months that you need to compare. Here’s how to make a handy summary for easy comparison:

Open both files you wish to compare in Excel. Take care to pick the sheet that will be compared in each file. In the main toolbar, choose the “View” tab. Then under the Windows section choose the option to “View Side by Side“.

The workbook will be automatically arranged horizontally in Excel, and both files will be displayed. You may now manually compare and modify these files.

Alternatively, you may use a third-party internet comparison tool. If you don’t want to spend time and need a fast comparison report, use the XL Comparator tool.

It’s a free tool that can handle Excel files not more than 5MB. All you have to do is upload the 2 files and tell the Comparator to look for data that is similar or different. The findings are available for download, and you may compare the marked similarities and discrepancies.

While this technique is useful and quick, it’s definitely not the ideal choice if you’re working with sensitive information.

How to Compare Files in Linux and Windows 10

In Linux

You may compare files in a variety of ways, including using the Visual Studio Code editor. The “diff” command, on the other hand, is one of the most common methods to compare text and code.

Most Linux systems come pre-installed with this command-line utility, which is simple to use. This is how the command line syntax looks:

“diff [options] First_File1 Second_File”
