In our company we have been using the App "Adobe Reader" on android tablets. It works linked with our ERP and we generate a pdf document through the app. The document, once has been sent by mail should be eliminated from the app. Instead every single document is saved on the app. How can i cancel this feature? It's very urgent because are very confidential files and can't remain on the app.
Open the app
Tap on Recent tab and then tap Clear Recent option from menu options
If you want to delete all the files which are under Local tab
then tap and hold a file and it will be selected and then keep on tapping more to make them selected.
Tap Trash Icon to delete those files
By this way all the PDF which are stored on the device will be deleted.
