Mobile App: File access no longer possible after a certain amount of time

English Import/export

Hello all,

Every time I save in desktop app the binary file, I want to send the file to my mobile app. So what i normally do is to save it as Binary and open the file with the phone.

Every first opening works perfectly, but then after few days i get an error message in my mobile phone so i cannot open the portfolio anymore. Any hint how to avoid that?

Many thanks!

And which error occurs?

Hi,

I renamed your topic, because that hasn’t to do something with the export to a binary file. Which OS are you using? Android? iOS? Is your file saved in a cloud or on the device directly?

Thanks for the support. I am using iOS and I used to save it in local in my phone before opening it with the PP app, therefore no cloud or anything else.

It is marked as Fehler in the portoflio file before trying to open it. No specific message, but I cannot open it

I am no iOS user, but there was a thing on which way you open it! Do you open the app and then there select the file? I think that was the correct way to do it!

If you click on the file in the systemviewer iOS is locking the access after some time for security reasons.

No, I think I did it in the other way around = open fiirst the file and then select the app to open it.

Try it the other way round. That might help.

I think one of the problems is that the mobile operating system gives permissions to the file only for a given version. If you overwrite the file (by saving it again), then the iPhone sees this as a new file and the mobile application has no permissions to read this file.

Either you open the file again (the app should detect it is the same file and keep mobile configurations).

What works is if you save the file from the PP desktop app directly on the cloud provider. You open the file from iCloud and then let PP save it to iCloud. This is the same file in the eyes of the mobile operating system and it remains.

Or you use one of the native integrations: DropBox, Google Drive, OneDrive. Here the app is using the API of those providers directly and therefore has permissions to read the file. The disadvantage is: you cannot give fine granular permissions to only the portfolio file (the app is not reading any other file of course - but that is the reason for the restrictive default model in the mobile operating systems)
