Solution 1Recommended

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.

1
Long-press the FTP Link

In your document or web browser, press and hold the FTP link for the PDF file until a context menu appears.

2
Download the File

Select 'Download link', 'Save target', or 'Save file' from the menu to download the PDF directly to your device's internal storage.

3
Locate the Downloaded PDF

Open your device's default File Manager app (such as 'My Files' on Samsung) and navigate to the 'Downloads' folder.

4
Open with a PDF Reader

Tap on the downloaded PDF file and select Adobe Acrobat Reader or another compatible PDF viewer to open it locally.

Download the PDF to Your Local Drive First
No Internal Setting Available: There is currently no setting within Adobe Acrobat mobile that can be adjusted to enable direct FTP link access. Downloading to a local drive is required.

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.
