Dropbox got cozy with Microsoft Office back in the spring, offering a way to easily edit files stored in its cloud-based repository. Now, Dropbox is getting friendly with Adobe Document Cloud, too. More specifically, the company is playing nice with Adobe Acrobat DC and Acrobat Reader to serve up quick and easy access to edit PDF documents. Once you connect your Dropbox account with the Adobe apps, you'll be able to pull in files without leaving the app. What's more, when you're browsing files in Dropbox, you'll have the option to open a PDF in the appropriate Adobe app to edit, e-sign, comment and markup the file as needed. And as you might expect, no matter how you open the document or which device you're using, everything automatically syncs in Dropbox across desktop and mobile. PDFs are by far the most common file format stored with the could-driven storage service,and now its improving the workflow for power users. The new functionality goes live on the desktop today with iOS integration arriving "in the coming months." Android users can expect to employ the PDF-editing workflow next year.
