Copy file from removable SD card - ASD (Taifun File Extension)

[Anke]

I cannot check it on Android 11+, because I do not have such advices with a removable SDcard. But I'm pretty sure that it works, if you try to read / copy a file from the app's own ASD.

I think I'm using a full path for the source file :

I need to see the full path here:

But the part of the path is NOT the ASD.

It should look like this:
...Android\data\appinventor.ai_bodymindpower.BluetoothClient_AI2test\files

Please, take a look at the previous screenshots

I used full path, but It is too long to show it on a single screenshoot..............

I think there could be a misunderstanding.
When I wrote "how can I read files (copy from) from ASD on removable SD card ?"
I referred whatever ASD, not ASD of the AI2 app.
In this case ASD folder name is "it.mydev.atrparkcontrol"

See my answer in post #6:

Using Taiufun File Extension I can copy a file to anywhere in the internal storage.

To almost anywhere (exept to the ASD of other apps).

And you have also no access at all to other ASDs, regardless of MANAGE_EXT...

[Anke]

... but you can access them with special file manager apps like "Total Commander" for example.

ASD

And again, the ASD in the (1) external storage & (2) external removable SDcard is:

(1) /storage/emulated/0/Android/data/<packageName>/files/ 
(2) /storage/9C33-6BBD/Android/data/<packageName>/files/ 

This ASD is only accessable for the app itself.
That's why it's called "App-Specific Directory".

[MengeneeringSoft]

So, "no access" means no read and write permissions........
I hoped there were possibility to almost have read access on all ASDs through AI2.
Thanks for your support.

The MANAGE_EXTERNAL_STORAGE permission grants the following:

• Read and write access to all files within shared storage.
Note: The /sdcard/Android/media⁠ directory is part of shared storage.
• Access to the contents of the MediaStore.Files table.
• Access to the root directory of both the USB on-the-go (OTG) drive and the SD card.
• Write access to all internal storage directories⁠, except for /Android/data/, /sdcard/Android, and most subdirectories of /sdcard/Android. This write access includes direct file path access.

Apps that are granted this permission still cannot access the app-specific directories that belong to other apps because these directories appear as subdirectories of Android/data/ on a storage volume.

This is not going to work.

The MANAGE_EXTERNAL_STORAGE permission grants the following:

To make it shorter:
It grants access (read/write) to all locations (except other apps' ASD) on

• external storage and
• (only) read access on a removable SD card (since API 19, Android KitKat).
