Correct, but when i did this where can i find the file?
Once a PDF document is exported to other file format (e.g. Word, Excel, PowerPoint), it will be saved to the Document Cloud.
You can tap the blue chevron in the top bar to open the Location Switcher and
(a) Select Outbox to check the status and tap the exported file to open it.
(b) Select Document Cloud to find the exported file and open it.
Please let us know if you have additional questions.
