Renaming slide files using
If a single presentation video is based on multiple presentations — for example, you
have several PowerPoint or Keynote presentation files to work with — you may
need to rename the slide image files that you export from PowerPoint or Keynote,
because Presto requires that each slide image has a unique filename.
In Windows Explorer, it's easy to rename a group of slide image files. When you select multiple files in a folder, Windows automatically adds a number
in parenthesis after each filename. The following steps explain how to use this
multiple file renaming feature:
- First, make sure all the slide files are sorted by name, then select them all, as illustrated below.
- Right-click on the first item and choose Rename from the drop-down menu.
- The text of the first item will now be selected, as illustrated below. Type a name for this presentation that is unique and will ensure that the
multiple presentations sort in the correct order (like Presentation 1,
Presentation 2, and so on).
- Now when you press Enter, Windows will rename all the files, adding a
number in parenthesis to make each filename unique, as illustrated below.
