Portable WinMerge

When you want to compare the contents of two or more documents, having a specialized application do the work for you can save you a lot of wasted time.

Such a solution is Portable WinMerge, and it can not only compare up to 3 documents at a time, but also folders.

As its name implies, this app is a portable one so no installation is required before you can enjoy its feature-set.

First off, you need to select the data you want to compare, no matter if they are files or directories, then save the project for future use. Moreover, you can narrow down the items from the selected folders by applying one of the supported filters, so only compatible files are taken into consideration.

There are multiple types of comparison methods supported by the app: full contents, quick contents, binary contents, modified date, modified date and size, or size.

If you decided to compare to contents of two or three directories, Portable WinMerge shows you the file dates for the items in each folder, while also informing you of whether certain files exist in each location.

When it comes to comparing documents, the differences are made obvious using colors, so you can easily spot the paragraphs that are not identical. At this point, you can choose to simply explore these differences, or to merge them.

If you need to combine the contents of your files, you have several options. You can copy all of the differences to the right or the left document, from the left or right document, or add synchronization points.

To wrap it up, Portable WinMerge can help you analyze your files and folders, compare their contents or merge the differences with only a few mouse clicks.
