Frequently Asked Questions

Why did my PDF suddenly disappear from Adobe Acrobat on my iPad?

If a PDF was opened from a temporary location, such as a direct email attachment or a browser cache, without being explicitly saved to your device's permanent storage, the iPad system may clear it to save space. It is always best to use the 'Save to Files' option when downloading important books.

Can I recover a deleted PDF book on my iPad?

Yes, if the file was accidentally deleted, open the Apple Files app, tap on 'Locations' in the sidebar, and check the 'Recently Deleted' folder. Files remain here for up to 30 days before being permanently erased, giving you time to recover them.

Where do downloaded PDF books usually go on an iPad?

By default, any PDF downloaded from Safari is saved in the 'Downloads' folder within the native Files app. Depending on your iPad's Safari settings, this folder might be stored locally under 'On My iPad' or synced to the cloud under 'iCloud Drive'.
