The Open function loads a previously saved slide show (.flk). Selecting Open from the File menu brings up a standard file browse dialog seeking saved Show (.flk) files.
Clicking on a file name will load the Show file and allow further editing or publishing operations. All properties of the loaded slide show will be active.
The Open function may be selected from the File menu, by entering the shortcut key command ctrl+O or by clicking on the Open icon
It is always good practice to save the slide show you are working on under another name so that you will not accidentally make undesirable changes.
