For slides with companion files, choose the whole folder containing the slide and its accompanying data. HEVC SDPC, fluorescence, z-stack navigation and Sakura formats are excluded. Support varies by scanner encoding.

Slides without a stored pyramid build their overview progressively. Use Open slide to add one slide and its companions at a time, then switch between tabs or compare two panes.

Workspace files save measurements and views, without slide pixels. To restore a workspace, import its JSON file and reselect the original slide files.
