ccdu vs Space Wizard

ccdu has no write-up on Specifiction yet; its figures are above.

Space Wizard scans files and folders on Windows, macOS and Linux, including external drives. Scan locations can include selected folders, whole drives, multiple drives, and shared or NAS folders. It can look for matches using SHA-256 content hashing, byte-for-byte exact matching, or recursive folder-content matching, and supports sending items to the Recycle Bin or Trash. Its Free plan costs nothing, is free forever, requires no card and covers the home drive up to 100 GB per scan. The product does not offer a treemap view, application sizes or a file-type breakdown. It also lacks automatic selection, so scan locations and matching methods are chosen by the user. Space Wizard is cross-platform and comes from a maker founded in 2024 and headquartered in Kragujevac, Serbia.
