You can use Selection menu or keyboard shortcuts to manipulate file selections in the file list.
Commands Select All, Select None and Select Invert are quite obvious.
Pattern selections
You can use filters to select and deselect files. When you choose one of these commands you can create a new temporary filter or load a named template.
Selecting similar files
Select one or more files, and then use Select similar... to add all similar files to current selection.
- by Extension: select all files with the same name's extension (or without extension)
- by Type: select files that are of the same type
- by Size: select files which size is +/- 10% size of currently selected files
- by Modify Time: select files which modify time is +/- 24 hours of currently selected files' modify times
- by Owner: select files that belong to the same owner
- by Group: select files that belong to the same group
Selection templates
You can use named selection templates to select or deselect files. Use Create Template... command to save current selection as a named template. Edit Templates... command opens a simple dialog with all defined templates listed in a tree view. There you can edit or delete them.
Summaries
Selection Summary command starts a summary counting utility. It counts how many files are selected including subdirectories and count types of these files. Also disk usage is counted. Default behaviour is not to dereference symbolic links, not count hard-linked files' disk usage and stay on the same filesystem when counting statistics. You can adjust these settings by using Advanced Selection Summary...
