My environment :
Visual Studio Community 2022 Version 17.5.4 and Xamarin 17.5 (Xamarin.android SDK 13.2)
Target platform android 12.1 (Samsung phone)
When I deploy a project to my phone via USB connection, application specific directories are sometimes erased.
This application-specific directories erased are documents directories ContextWrapper.GetExternalFilesDirs(null)[0 or 1].AbsolutePath, ie
- /storage/0123-4567/Android/data/Myapp/files
- /storage/emulated/0/Android/data/Myapp/files.
Sometimes only files are erased, sometimes directories cache and files are itself erased (I don't use others specific directories).
I am an occasional user of Xamarin. I had never encountered this problem before.

Where did you check these files? With
Fileapplication, device file explorer or other tools?You can test it in the android emulator, is this issue happened?

2023-05-02T09:49:34.85+00:00 Is explorer Cx Explorer third-partly application?
If so, you can use adb shell command to check personal files exist with emulator(start adb command with Tools > Android > Start Android Adb Command Prompt.).

2023-05-02T13:51:54.0933333+00:00 I use ALPHAINVENTOR Cx File Explorer V 1.9.8 or the file explorer of my WINDOW computer.
You know that since android 10 or 11, android explorer denies access to specific files (even my own files), and access to non specific files (in the the root directories) was denied to my applications, unless using MANAGE__EXTERNAL__STORAGE (https://learn.microsoft.com/en-us/answers/questions/1240227/acces-to-files-with-xamarin-android-(solved)).
I am a self learning C and Xamarin languages user, not very familiar with adb toolbox. But I'll study your suggestion.

2023-05-03T07:52:09.61+00:00 ALPHAINVENTOR Cx File Explorer is a third-party application, If you want to check the file path. Please use adb tool with android emulator, we can exclude the device or third-party application issue.
