Please always post a link to it (and "if possible", spell the (my) name correctly ("Anke"):

How do you copy file (taifunfile copyasync) to folder in internal storage (android 11)?

Try this app with Companion and the complied app (APK): saveToShared.aia (2.3 KB) [grafik] And see also here:

This test aia works fine.

Try also this test app (and follow the notes): saveToShared_2.aia (3.0 KB)

Non-media file that are saved in one of the Shared folders (/Documents or /Download) MUST be created by the app itself. The APK and the Companion app are different apps. So the text file must be removed before testing (with Companion or APK beforehand).
