Fix Adobe Acrobat Cloud Storage Error on Amazon Fire 7 Tablet
Product
Adobe Acrobat Reader
Device & OS
Amazon Fire 7 Tablet (Android)
Scenario
Uploading or downloading PDF documents using Adobe Document Cloud on a mobile device.
Observed behavior
The application returns a 'Not enough available memory' error message when attempting an upload, even though both the local device and cloud storage appear to have plenty of available space.
Before you start

Verify the exact file size of the PDF you are trying to upload, as mobile applications often have strict data limitations compared to their desktop counterparts.

Solution 1Recommended

Check PDF File Size and Document Cloud Quota

Ensure your document complies with the Adobe Acrobat Android app limits and your free account storage quota.

Free Adobe Document Cloud accounts are strictly limited to 2 GB of total storage. Furthermore, the Acrobat Reader application for Android and Amazon Fire tablets has a hard limit: it cannot upload or download individual files larger than 100 MB. The 'Not enough available memory' error is usually triggered when these invisible thresholds are crossed.

1
Verify the PDF File Size

Open the 'Files' or 'Docs' application on your Amazon Fire 7 tablet. Locate your target PDF, long-press the file, and tap 'Properties' or 'Details' to confirm it is under 100 MB.

2
Check Available Cloud Storage

Log into your Adobe Document Cloud account via a web browser. Check your account settings to verify that your uploaded files have not exceeded the 2 GB limit for free accounts.

3
Locate Downloaded Files

Use your tablet's file manager to check the local 'Downloads' folder. PDFs downloaded through Acrobat Reader are saved directly to local storage rather than being kept inside the application itself.

Local Storage Difference: Deleting files from within the Acrobat Reader app's recent list might not delete them from your tablet's internal storage. You must use a file manager to free up physical device space.

Frequently Asked Questions

Why does Adobe Acrobat say 'Not enough memory' when I have plenty of storage?

On Android and Amazon Fire tablets, this error is a default message triggered when you try to upload a PDF larger than 100 MB, or when your total Document Cloud storage reaches its 2 GB free limit, regardless of your tablet's local free space.

Where are my downloaded PDFs saved on the Amazon Fire 7 tablet?

Files downloaded via the Adobe Acrobat Reader app are saved to your tablet's local storage. You can find them by opening the built-in 'Docs' app or a file manager and navigating to the 'Downloads' folder.

Can I increase the 100 MB upload limit on the mobile app?

No, the 100 MB file limit is a hard restriction coded into the Adobe Acrobat Reader application for mobile devices. To manage larger files, you must use a desktop computer or a web browser.
