Commander Tab

The Explorer style selection checkbox switches to Explorer-style selection of files.

When Do not change state of local panel when switching sessions checkbox is checked, the local path is not changed in local panel, when sessions are switched. It also suppresses effect of Remember panels state when switching sessions for local panel.

The Swap panels checkbox reverses order of local and remote file panels.

The Use Location Profiles instead of Directory Bookmarks checkbox toggles between the two modes of bookmarks.

The section defines criterions for comparing content of directories (file panels), using Commands > Compare Directories.

Compare by time makes the command select (highlight) files that exist in an opposite directory, but have newer timestamp (the file is selected in one panel only).

Compare by size makes the command select (highlight) files that exist in both directories, but have different size (the file is selected in both panels). Compare by time has higher priority than Compare by size.

The files not existing in an opposite panel are selected (highlighted) always.

Note that while you can check both options, you cannot uncheck both.
