*New in TIF Reader 3.2 - we've added better support for large TIF files! This should reduce the number of times this issue occurs.
Opening large TIF files can be problematic for devices that are low on memory.
Option 1) Try closing out other apps from the background to free up memory for loading the file.
Option 2) Check your available space on your device by going to Settings->General->Usage. Once the list builds you can see what other apps may be taking up storage. You can free up space by removing any unused apps.
