Enabling this feature will cause embedded objects within Office files to be "flattened", converting them into pictures. This will reduce the size of the files but users will no longer be able to double-click embedded objects to edit them.
For example, a PowerPoint presentation may contain an embedded Excel sheet with a table of figures. Double-clicking the table would normally open Excel to edit the figures, but flattening the document converts the table to a simple picture, meaning the underlying data cannot be edited.
If NXPowerLite has "flattened" embedded objects then a message will be shown under the file name in the Results window. To optimize files without "flattening" embedded objects choose one of the "no flattening" Optimize profiles or a custom profile.
