I like your response. I noticed that you are a member of the staff, whatever
I recommend that a documents tab be added to Adobe Acrobat DC, such as was
available in the latest version of Adobe Reader. As before the change,
clicking on the tab would list all of the pdf files currently on the device
and their present folder location instead of having to open every folder to
try and find the document. This would be a lot easier and quicker.
my files are just gone. I have paid patterns, online magazines, etc. in my adobe reader files. This just makes me sick. why couldn't you tell us so we could get our files moved out of adobe. You took a great thing and killed it. Bah!
We are actively trying to bring back the 'Documents' tab. Sorry for the inconvenience.
All your files are still present on your device and are not deleted? Were your files stored on your device or on Acrobat.com? If they are located on your device, you can follow the steps at How to open PDFs on Adobe Acrobat DC on Android to access them. If they are located on Acrobat.com, would you ensure that you are signed in to your account and find them under the 'Document Cloud' tab(the new name for Acrobat.com)? We are actively trying to bring back the 'Documents' tab which listed all the local PDF files in one place. Sorry for the inconvenience.
