How to Fix Adobe Acrobat Mobile Cannot Download PDFs from FTP Links
Question details
The user is unable to open or download PDF files directly from FTP links using Adobe Acrobat Reader on a mobile device, despite other formats like JPEG working correctly.

- Product
- Adobe Acrobat Reader Mobile
- Device & OS
- Android (Samsung Galaxy S8+)
- Scenario
- Clicking on an interactive document linking to a PDF file hosted on an FTP server.
- Observed behavior
- The app displays the error message: 'Cannot download file. Save the file to a local drive and then try to open it.'
Ensure your mobile device has a stable internet connection and access to a built-in web browser or file manager capable of downloading files to local storage.
Download the PDF to Your Local Drive First
Since the mobile version of Adobe Acrobat lacks direct FTP support, you must download the file using your browser or file manager before opening it.
Unlike its desktop counterpart, Adobe Acrobat Reader for mobile is a streamlined application and does not feature built-in capabilities to directly access or stream PDF files hosted on FTP servers. Therefore, it requires the file to be present on your device's local storage.
In your document or web browser, press and hold the FTP link for the PDF file until a context menu appears.
Select 'Download link', 'Save target', or 'Save file' from the menu to download the PDF directly to your device's internal storage.
Open your device's default File Manager app (such as 'My Files' on Samsung) and navigate to the 'Downloads' folder.
Tap on the downloaded PDF file and select Adobe Acrobat Reader or another compatible PDF viewer to open it locally.

WPS Office is a powerful, all-in-one mobile suite that effortlessly handles PDF reading, editing, and annotation. Once your PDF is downloaded locally, WPS Office opens it instantly with smooth rendering and advanced viewing features.
- 1. Download the PDF Locally: Save the PDF file from the FTP link to your mobile device's local storage using a browser.
- 2. Launch WPS Office: Open the WPS Office app on your mobile device and navigate to the 'Files' tab.
- 3. Locate the File: Tap on 'This Device' or navigate to the 'Downloads' folder to find your saved PDF.
- 4. View and Annotate: Tap the PDF to open it instantly. Use the intuitive toolbar at the bottom to highlight, annotate, or edit the document.

Frequently Asked Questions
Why do JPEG links work on FTP but not PDFs in Adobe Acrobat Mobile?
Mobile operating systems and built-in web browsers have native support for rendering image files like JPEGs, allowing them to open seamlessly from FTP links. PDF files, however, require dedicated rendering engines. Adobe Acrobat Mobile does not support live streaming of these files from FTP protocols.
Can I change a setting in Acrobat Reader mobile to allow FTP access?
No, Adobe Acrobat Reader for mobile currently lacks native support for direct FTP access. There are no configurable settings to bypass this limitation; you must download the file to your local drive first.
How do I find downloaded PDF files on my Samsung Galaxy device?
You can locate your downloaded PDF files by opening the 'My Files' application on your Samsung device. From there, navigate to the 'Downloads' folder, where you will find the saved PDF ready to be opened in your preferred viewer.
