Delete Extra Stuff to Speed Up CorelDRAW
Saved Views: Open up the View Manager (Window | Dockers | View Manager or Ctrl + F2). Unless you have specifically saved Views, the Docker should be blank. If it isn't, click on the first view and Shift + click on the last view. Press the - icon at the top of the Docker and they will all be deleted. I've seen files with hundreds of saved views.
Graphic and Text Styles: Open up the Graphic and Text Styles Docker (Window | Dockers | Graphic and Text Styles or Ctrl + F5). There are a handful of styles that should be there by default. Those include: Default Artistic Text, Default Graphic, Default Artistic Media and Default Paragraph Text. Those are mandatory and control defaults for each type of element. You will also see Bullet 1, 2 and 3 plus Special Bullet 1, 2 and 3. Personally I don't find those useful at all. If there are other styles listed that you haven't created, you need to delete them. Click on the first "bad" style and Shift + click on the last "bad" style. Press the Delete key. Repeat until all of the "bad" styles are gone. I've seen files with thousands of extra styles.
Color Styles: Open the Color Styles Docker (Window | Dockers | Color Styles). You'll see a folder representing each file you have open. Double-click the folder for the currently active file. If you've created color styles, you'll see them listed. Many times you will see hundreds of color styles that you didn't create. Click on the first one and hold down the Delete key until they are all gone.
Believe me, it can be a hassle to scrub your files of this extra junk. But if you take the time to clean up your files, you'll find that things run much faster.
