The best thing about the app is you can either choose to install it or run from a portable ZIP file. The app also supports the analysis of external storage devices. You can export the disk space analysis to a CSV, text or HTML report. You can choose to clean up files from within the app. The moment you select the directory you want to scan, it pops up their list with size, percentage and file count. It has a familiar Windows Explorer-like interface and you would instantly relate to it. If you are looking for a file analyzer with minimal features and zero learning curve, then RidNacs should be the one. You even get a graphical representation of the same and some of them even go ahead in printing the analysis. They analyze the files on your disk and report information such as file size, file percentage, and duplicate files. They are significantly small in size and give you substantial information about your storage. So, here is where 3rd party Disk Space Analyzers come in.

That’s it, you cannot see file names, file size or even apply custom filters. It’s quite basic and gives you a summed up information about the types of file on your disk. In fact, there is one inbuilt (somewhere hidden in System Settings).

Now, when it comes to Windows, there is no shortage of 3rd party disk analyzing apps.
