Some of them even let you remove files directly from the program.

Categorizes files in several ways.
Regular updates to newer versions.
Scan multiple locations simultaneously.
Export results to a report file.
Works within File Explorer.
Some features require the paid Pro edition.
Only 500,000 files per scan.
I list Disk Savvy as the No.
There’s a professional version available, too, but the freeware edition seems perfect.
Disktective
Portable.
Scans large files in a specific folder or the whole drive.
Provides two ways to view disk space usage.
Export the results to a file.
Unable to delete files directly from the program.
Exported results are hard to read.
Only Windows users can install.
An update hasn’t been released since 2010.
This would be great to carry with you on a flash drive.
Each time it opens, you’re asked what directory to scan.
TreeSize Free
Lets you remove files from within the program.
Scan individual folders and entire hard drives.
Supports internal and external hard disk drives.
Doesn’t work on Linux or macOS.
Filtering options aren’t super helpful.
No unique perspectives are available as with similar tools.
This definitely beats having to scour your hard drive for those files just to erase them.
Get the portable version if you want to run it without installation.
Only Windows can run TreeSize Free.
Windows Directory Statistics (WinDirStat)
Scan a whole drive or a single folder.
Provides unique ways to visualize disk space.
Can configure commands to delete data.
Unable to save scan results to a file you’re free to open later.
A bit slower at scanning than similar tools.
Runs only on Windows.
WinDirStat works on the Windows operating system.
In fact, you could use it even if you’re still running Windows 95!
I tested it in Windows 11.
SpaceSniffer
Results can be filtered several ways.
Results can be backed up and opened again without rescanning.
Delete files from inside the program.
Report of large files can be saved to a text file.
Can be hard to grasp at first.
Works only on the Windows operating system.
No longer receives updates.
The filter feature lets you search through the results by file throw in, size, or date.
you could export the results to a TXT file or a SpaceSniffer Snapshot file.
JDiskReport
Shows disk space usage in five perspectives.
Interface is ideal for new users.
Works on Windows, macOS, and Linux.
Doesn’t let you delete files from within the results.
Noticeably slower than other options.
JDiskReport displays file storage in list view or via a pie chart or bar graph.
Windows, Linux, and Mac users can use JDiskReport.
RidNacs
Minimal and simple interface.
Won’t run on Linux or macOS.
Missing advanced features found in similar applications.
I’d say its clear and simple design makes it more appealing to use.
This program can scan a single folder or whole hard drives.
I do this often for myDownloads folder.
Folder Size
Integrates with File Explorer.
Sort folders by size.
Shows results in an extra window instead of the window you’re viewing.
Runs only on old versions of Windows.
Long time since the last update.
With Folder Size, you might see the size of each folder in a small window.
The user interface is nothing like the other analyzers in this list.
Otherwise, this looks to be a decent program only for Windows XP users.
