If you are currently using the free version of Zip Viewer and want to switch to the Pro version, your files can easily be migrated via iTunes on you computer.
1. Download all files on your computer
Connect your iPhone or iPad to your mac (better via USB) and open iTunes. Both versions free and pro need to be installed on your device.
Go to the iTunes file sharing section (select your device in iTunes).
Click on the free version and download (save as) the folder “workbooks”, which should have appeared in the box documents on “Zip Viewer” on you computer.
2. Upload to Zip Viewer Pro
Click on the pro version and push the button Add, choose the (beforehand downloaded) “workbooks” folder.
Important: choose “replace”, when the dialog appears.
Restart the pro app and the files should appear as in the free version.
Note: If you have already files in the pro version this procedure will delete them.
Tip: If you want to merge files for free and pro, do this on your computer before uploading. But, keep the sub-folders in “workbooks”, otherwise the app might not be working properly.Tags: backup data exchange feature files ipad iphone migrate migration pro user guide viewer zip zip viewer
