The InDesign plug‑in modules are software programs developed by Adobe, and by other software developers working in conjunction with Adobe, to add features to Adobe software. A number of importing, exporting, automation, and special-effects plug‑ins come with your program and are automatically installed in the Plug‑Ins folder. In fact, most of the features you see in InDesign are provided by plug‑ins.
Once installed, plug‑in modules appear as options on menus, in dialog boxes, or in panels.
You can use any commercial plug‑in designed for use with InDesign. Adobe Technical Support can help you isolate problems related to plug‑ins. However, if it has been determined that the problem is directly related to a plug‑in created by another company, you will need to contact that company for further support.
Use the Extension Manager application to inspect and customize the set of installed plug‑ins. For example, you can get detailed information about installed plug‑ins, create custom plug‑in sets for different tasks or workgroups, and isolate plug‑ins when troubleshooting problems. You can also disable plug-ins.
