MFile - a modified version of Sunny's `EFile` extension - Shared folders - storage permissions - Android 11+

[patel]

I would gladly use saf if it was possible to avoid the file list, I already know the location of my file

@patel

I don't understand the advantages of mfile ext over file component.

you are again asking the same questions, which already have been answered...
it does not look like you read the first post in this thread as previously suggested...

Conclusion
As long as the bugs with the File component are not fixed, I recommend using this extension (MFile), at least on Android 11+.

But if you want to stick with the File component, you MUST ALWAYS set DefaultFileScope to Legacy. Otherwise it will not work on Android 11+ or you MUST save in the ASD or PrivateDir (internal storage).

I'm asking the same questions, all you are repeating the same answer, no one tries to explain to me in other words

[Taifun]

What about telling us, what exactly you do not understand after reading the answer?

[patel]

Can I with mfile read/write a text file created by another app in the shared folders ?
If yes what is wrong in my blocks ? (post 24)
If not why I should use this extension instead of using file component ?
Please don't tell me see first post again, you don't have to answer me.

What could be misleading about this statement?

So for Android 11+ the statement is and remains NO.

So how about you read the links and hints we have posted thoroughly and carefully?

@Anke

So for Android 11+ the statement is and remains NO.

It's clear, now what's the goal of mfile ext ? please explain me as a kind.

[Anke]

@patel

now what's the goal of mfile ext ?

It is absolutely impossible (and inconceivable even after all these additional and actually superfluous explanations) that this question is really meant seriously!

[patel]

For 20 days I'm trying to understand what this extension is for and no one answers me, and you get angry...
In the past you have helped me a lot, I wonder why this closure

[Anke]

@patel

For 20 days I'm trying to understand

So for the very last time:

Read this (again?), which takes a by far less than 20 sec (20 days? ).

@Anke

Try this app. It saves a text file in the Shared folder /Documents. It should work without storage permissions on Android 11+ using the MFile extension.
If you try do use the File component (Checkbox disabled), you will get a permission error ("Error 908: The permission WRITE_EXTERNAL_STORAGE has been denied. Please enable ..."). In order to work with the File component you MUST set DefaultFileScope to Legacy in the Designer.

If you then still don't understand, no one will be able to help you.

[patel]

@Anke

Try this app

I can not find any app in this thread

[Anke]

@patel

I can not find any app

OMG, see here:

[patel]

I give up understanding, I will continue to use AllFilesPermissions
Thank you all

[Anke]

@patel

I give up understanding

There is also a video that explains/shows it crystal clear.

@patel

For 20 days I'm trying to understand what this extension is for

to workaround the unnecessary permissions, the file component is asking for
see also this thread, which might help to better understand the problem

How to request and grant MANAGE_EXTERNAL_STORAGE permission

there's something wrong... according to your https://community.appinventor.mit.edu/uploads/default/original/3X/4/0/40cd49dd497957af9973789392bc0b679d1ca8f6.jpeg I should not need any permission to write and read a text file generated by the app from /Download. In fact testing under appinventor it does ok! Building the apk, when reading if there is no file, the app stops telling "file not found" but if I hand copy the file into /Download it stops telling "no permission.."; and that's also ok. …

@patel

I give up understanding

this is your choice... alternatively if you do not want to use the MFile extension, you always can use the file component and live with its limitations

Taifun

[patel]

With File component (set to Legacy) I can save a text file in shared folders and read it, what's the limitation ?
With MFile ext I can save text file in shared folders and read it, what's the difference ?
Both cannot read files created by other apps.
Please explain me without links

Is that now finally clear enough?

[patel]

It's clear now, but it doesn't seem like a big limitation to me

[Anke]

@patel

It's clear now

Hallelujah
I can hardly believe it.

@patel

but it doesn't seem like a big limitation to me

It is not only a limitation, but a bug.

[patel]

It was really worth creating an extension to just overcome this bug?
Or does this extension do more?
