Other Options

Czkawka also lets you delete Empty Directories, Big Files, Empty Files, and Temporary Files. You can even search multimedia content to find matches. In the Similar Images tab, search for image files. You'll need to specify the minimum size and also determine the degree of matching.

Once the entries appear in the table, click an entry to view the data. A visual preview of image file data helps to ensure that the files listed as duplicates actually match (Figure 4).

Another unique feature of Czkawka is the Music Duplicates tab, which detects duplicate audio files. In this dialog, you can also specify a minimum size. Additional criteria define metadata, such as the title, artist, or album title, which the tool takes into account during the search.

Additional parameters let you include files that no longer contain data, invalid symbolic links, and corrupt files in the list. The Zeroed Files option primarily means logfiles emptied by the system, which therefore return a file size of zero bytes when queried.

The Zeroed Files option, like the Invalid Symlinks and Broken Files options, offers no further setting. Pressing Search starts the search directly. For invalid symbolic links, as well as for corrupt files, the table gives the error sources, so you can decide whether you want to delete the files. In all categories, select the datasets you want to remove, and then click the Delete button.

Conclusions

Czkawka gives users a universal tool for removing old data files. The software takes an approach that is different from tools such as BleachBit. Instead of application-specific data, Czkawka takes duplicates and temporary content, which can consist of multimedia data and emptied logfiles. Czkawka is also useful for deleting oversized files such as ISO images.
