There are three options to share documents in Docutain:
Those are explained as follows:
1. Send directly after scanning
Scan the desired document as usual or import an image or a PDF-file via the import functionality. Afterwards the edit mode opens.
Tap on the “share icon” in the upper toolbar and select if you want to share your document as PDF or JPG. You can save the document after sending or mark it as "delete afterwards", if the file is no longer needed.
A pop-up opens, in which you can select the right app for sharing the document.
2. Send a saved document
Display the appropriate document and tap on the “share icon” at the top of the display as shown in the picture. Tap on “share”. Another pop-up appears, in which you can select the right app for sharing the document.
3. Send multiple documents at once
Select “recent documents” in the menu.
Tap the “three dot icon” in the upper side and choose "select multiple”.
Pick the appropriate documents you want to share and tap “share”:
A pop-up opens, in which you can select the right application.
Alternatively you can also use the “search” first, to get only relevant documents and then select and share the desired documents, as described.
