How to SAFELY Redact Documents on Adobe Acrobat 9

OK ...we've all been there. A late night redacting hundreds of documents and at some point we go into zombie mode and we override a document instead of making a new one. The sun comes up and your boss rolls in and asks for that ONE document (unedited) that you overrode .....arrrrggggggggg! 

Med Art is here to help you avoid that altercation.

Automatically Rename Redacted Files

When Acrobat applies redactions, the text, image or data is permanently removed and cannot be recovered. For this reason, Acrobat will give you a stern warning when you apply redactions:

The operative message above is that when you apply redactions you will be prompted to rename your document the next time you save your document.

Let's say you ignore this warning and try to save over your original document. You'll receive another warning similar to the one below:

If you ignore this warning, you can save over your original file.

To protect against accidentally saving over a file, you can set a preference to automatically rename redacted documents.

Here's how:

1. Choose Edit—> Preferences (Windows) or Acrobat—> Preferences (Mac)
2. Select the Documents category from the list on the left:
   
   
3. At the bottom of the window, enable the check box labeled "Adjust filename when saving applied redaction marks"
   
   
4. Click OK

The next time you apply redaction marks and save your document, Acrobat will automatically include the _Redacted suffix in the Save dialog:
