If you have limited storage space on your computer or you struggle for some space on your hard drive from time to time, it is always a good idea to keep removing unnecessary files from the hard drives to have more room for things that matter to you. But when it comes to analyzing the used and available space on a hard drive, you should choose some utility software that can help you observe and manage the files on your Hard Drive or any other storage in the simplest way. The good thing is, whatever operating system you are using, you will always find some utility programs that can help you to manage storage on your hard drive.
Quick Install Steps: Step 1. Sudo apt-get update -y. Sudo apt-get install -y qdirstat. Check the system logs to confirm that there are no related errors. You can use ZoomAdmin to check the logs, manager servers, host multiple websites and apps on your servers and more. QDirStat is a graphical application to show where your disk space has gone and to help you to clean it up. This is a Qt-only port of the old Qt3/KDE3-based KDirStat, now based on the latest Qt 5. It does not need any KDE libs or infrastructure. Web、Android、iPhone、Windows、iPadなどの QDirStat の代替。 ライセンスでフィルタリングして、無料またはオープンソースの代替のみを発見します。 このリストには、QDirStat に類似した合計 7 個のアプリが含まれています。. If QDirStat finds a file.qdirstat.cache.gz in a directory, it checks if the toplevel directory in that cache file is the same as the current directory, and if it is, it uses the cache file for that directory rather than reading all subdirectories from disk. KDirStat was a graphical disk usage utility for KDE 3, very much like the Unix 'du' command. In addition to that, it came with some cleanup facilities to reclaim disk space. But it's history now. Use the newer QDirStat or K4DirStat instead.
Talking about Linux, which is an open-source platform, you can also find several similar programs on Linux, and you can use one or many of them to manage the storage space on your hard drive or SSD. Even if you are not struggling for space on your storage device, it is always a grand idea to have such utility installed on your system, so that you can use it whenever you find that useful. So, today I will talk about the top 10 disk space analyzer tools that you can use on Linux.
Best Linux disk usage analyzer software 2021
Without any further delay, let’s get started with the list of free + opensource utility programs to analyze disk space on Linux distribution and have command over the storage space on your hard drive and SSD.
QDirStat
If you have ever used WinDirStat on your Windows computer, you will feel at home by using QDirStat. QDirStat is based on KDirStat, and WinDirStat is also based on the same. If you haven’t used WinDirStat on your Windows computer, let me give you a brief introduction to QDirStat. With the help of QDirStat, you can analyze the complete disk space on your Linux system, and the content will be displayed as square blocks. Depending upon how big a particular square block is, that actually reflects the actual size of the individual file on the hard drive, and as you have understood, the bigger the square, the bigger will be the size of the file and vice versa.
QDirStat Disk Analyzer for Linux
You can also click on any of the square blocks, which is very easy to observe, to find out what the file is and decide whether you should delete the file or not. That way, you can click on every big block to find out the actual file and make the decision to delete it. Depending upon the individual files, it might take some time to show you the name of the file, but that’s not significant. QDirStat also comes with additional features, which can make it easy for you to free up space on your computer’s storage. You can download it across many different Linux distributions which is yet another reason I will definitely recommend QDirStat.

Trust me it is one of the simplest tools that you can use on your Linux System to analyze disk space. Even though you cannot visualize the files on your storage device exactly the way as QDirStat in this program, you should choose this program if you are looking for an easy-to-use tool to analyze the available disk space on your storage device. The complete storage space on the hard drive or SSD will be displayed in the form of a pie chart which makes it easier for most users to manage the disk space.
As the user interface is very simple, it is many people’s favorite, and the software is capable enough to scan the full file system at once, or it can also track the individual folders chosen by you. The ball is in your court, and you can use the software exactly the way you want. You can also manage remote storage locations using FTP, SMB, HTTP, and other common protocols. Talking about the other advantages, you can also configure the software to always keep a tab on the changes made in the home directory, which can also save you some disk space at regular intervals.
