 iOS 11
The outdated GoodReader 3 apps were discontinued in 2014 and replaced with the modern GoodReader 4. If you’re still using one of the older 32-bit GoodReader 3 apps, they will not work in iOS 11 which only supports 64-bit apps.
If you’ve updated to iOS 11 and need to recover your files from GoodReader 3, you can copy them to your computer via USB. You can do this with our free GoodReaderUSB file transfer tool for your computer or you can use iTunes File Sharing, then transfer the files from your computer to GoodReader 4 using the same tool.
