Sothink SWF Decompiler enables you to modify SWF resources directly right after previewing them. Switching to Adobe Flash to make a new SWF is not a must. You can edit Shape and Text; replace Image and Sound.
Note: After modification, the edited elements and the corresponding resource folders will be marked with * once one or more elements are edited. You can easily find the modified elements by this mark. (See 1 in following image)
