Speed Loading of PDF FilesIf you'd like to load PDF files faster, follow these simple instructions:
- Launch Windows Explorer
- Navigate to the Program Files folder, usually C:\Program Files
- Below this, navigate to Adobe\Acrobat 6.0\Reader
- In the right-hand pane, find the folder named plug_ins
- Right-click it and choose Rename, changing it to plug_ins_NOT
- Create a new folder named plug_ins
- From the plug_ins_NOT folder, copy just three files to the new plug_ins folder: EWH32.api, printme.api, and search.api
It works, Acrobat Reader does load up faster without problems
