DiskMize is a desktop disk-space analyzer built with Python and Tkinter. It lets you scan a directory or drive, inspect discovered files and their sizes, and decide what needs further attention.
The interface is available in English and Spanish and includes file-location actions, scan controls, and configurable appearance options.
Warning
Deleting files is permanent. Review file paths and selections carefully before confirming a deletion. DiskMize does not use the recycle bin for its deletion operation.
- Scan directories and drives to inspect files and folders.
- Review file sizes and identify where storage is being used.
- Search for files using the application's search field.
- Open or reveal items using the available file-manager actions.
