You can compare files that are stored in the same folder in a project or a library or in the same task.

1. Open the first file that you want to compare in Smart Review.
2. You now have options to compare files in side-by-side or stacked view. Click the Compare View Options button to select your view. Select Synchronize View to synchronize comparing files.
3. Click Compare View .
   • Side-by-Side view:
     The viewing area is split into three sections. The left and middle sections contain the images to compare, and the right section contains the comparison image.
     If the file that you opened has multiple revisions, the most recent revision of the file automatically appears in the left section and the next most recent revision of the file automatically appears in the middle section
     If the file that you opened is a page in a multipage file, the first page of the file automatically appears in the left section and the next page of the file (from the Elements in Session window) automatically appears in the middle section.
   • Stacked view:
     The viewing area is split into three sections. The top and middle sections contain the images to compare, and the bottom section contains the comparison image.
     If the file that you opened is a page in a multipage file, the first page of the file automatically appears in the top section and the next page of the file (from the Files pane) automatically appears in the middle section.
4. Perform one of the following actions:
   
   • If the second file that you want to compare is a single-page file, right-click (Ctrl+click on a Mac computer) the file and select Assign to Middle View.
   • If the second file that you want to compare is a multipage file, click the name of the file to view each page in the file. Right-click the specific page that you want to compare and select Assign to Middle View
   The comparison image in the right section is automatically refreshed to display any differences between the two selected files.
5. View the comparison image.
   Tip: If the images being compared are identical except for their page dimensions or positioning, you can use the Align Images feature to align a specific point on one image with a specific point on the other image.
6. When you are finished comparing the two files, click Single View  to return to viewing one file at a time.
