Users of Adobe Acrobat DC and Adobe Acrobat Reader can now access and take common actions on PDF files stored in Dropbox directly from within the Adobe apps, it was announced this week. Dropbox users can open, edit, and save changes to PDF documents in the Adobe apps directly from the Dropbox website, iOS app, or Android app. The two companies say the integration addresses a strong need, as PDF is the most common business file type in Dropbox.
