Optimizing Files


When you add data to PDF files, such as making comment notes, Adobe Reader keeps track of all your edits. If you add a note and delete it, the deletion doesn't return the document to its original file size. As a result, the file size tends to swell more than needed to preserve all the data. When you use the Save command, you're saving that oversized file.

As an alternative, you can rewrite the file to disk and eliminate any redundant data, producing a smaller, optimized file. To do this, use the Save As command.

Use the hawaiiNewsletter.pdf file from www.peachpit.com/adobereader7.


To optimize files enabled with Adobe Reader usage rights:

1.

Open a file in Reader for which usage rights have been enabled, or use the hawaiiNewsletter.pdf file.

2.

Make an edit in the document such as adding a comment note.

3.

Open the Preferences dialog by pressing Ctrl/Command+K.

4.

Click General in the left pane.

5.

Check the box for Save As optimizes for Fast Web View (Figure 10.4). By default the item should be checked in the General preferences. If it's not, check the box. This option optimizes your file each time you use the Save As command.

Figure 10.4. Check the box for Save As optimizes for Fast Web View.


6.

Select File > Save As. By default the target folder is the same location where you opened the original document. Click Save in the Save As dialog, and a warning dialog appears informing you that the file already exists and asking whether you want to replace the existing file.

7.

Click Yes in the Save As warning dialog (Figure 10.5). Adobe Reader overwrites the PDF document and optimizes it for the smallest file size.

Figure 10.5. Click Yes, and the file is rewritten with optimization.


Why can't I overwrite some files?

If you copy files from CD-ROMs or other sources, your files may be copied to your hard drive as read-only files. If you attempt to save a read-only file by overwriting the original, an Adobe Reader warning dialog will open as shown in Figure 10.6. Read-only files can't be overwritten. However, if you have a number of files saved as read-only, you can change the properties of those files before opening them in Adobe Reader to make them read-and-write files.

Figure 10.6. If you try to overwrite a read-only file, Adobe Reader displays a warning dialog informing you that you can't do it.


In Windows you can change read-only to read-and-write status for a single file or a folder of files. Navigate to the folder containing the files, and open a context menu. Select Properties from the menu. The Properties dialog opens (Figure 10.7). If the Read-only check box contains a checkmark or a square, click the check box to remove all marks. Click OK, and the files in the folder are changed to read-and-write status.

Figure 10.7. Open the folder properties and remove all marks from the Read-only check box.


On the Macintosh, select a folder and select File > Get Info or press Command+I to open the Info dialog. At the bottom of the dialog (Figure 10.8), open the Ownership & Permissions collapsible menu by clicking on the right arrow. From the You can pull-down menu, select Read & Write.

Figure 10.8. Open the Info dialog on the Macintosh and select Read & Write from the You can pull-down menu.


After removing read-only protection from the files, you can overwrite the files in Adobe Reader.
