Convert the TinyDB to file:

guardar_tiny.aia (3.1 KB)

you can also use this extension TinyDBX

Where will the file be stored after converting? in the sd card or android?
Or does it not change?

Neither nor. But in the Private directory (→ Internal Storage):

/data/user/0/<packageName>/files/

Btw, what do you mean with "android"?

The idea of my example was to create the file in "internal storage" and share it.

Works with Companion, but not installed.
shareng

Question for @ewpatton, please.

Is it possible to create a file with File component in "program private data directory" and share it?

shareng2

No, even not with the TaifunSharing extension:

Spotlight · August 16, 2020, 11:59am

The thing is, the files are not in sd card. In fact my device does not even have an sd card. So, all the files are in the internal storage...So, I think the more appropriate question to ask would be, is it possible to share files from the internal storage?

Anke · August 16, 2020, 2:24pm

Each device has a virtual SD card (which, from Android's point of view, is an External Storage).
You are obviously talking about a removable (micro) SD card.

the answer is yes
to share a file form the assets first copy it to the internal sdcard and share it from there

Not at this time, but it seems like something we could (and should) support.

Edit: Filed this as an issue on GitHub:

Allow sharing files from app private data directory

help wanted issue: noted for future Work status: new feature request affects: master priority: medium

**Describe the desired feature** When using the Sharing component, allow file…s in the private app data directory to be shared. Currently, the ShareFile method prepends "file://" if the filename doesn't start with that, and tries to load said file. If "foo.txt" is written with the File component, it is written to the app private data directory. If this relative path is given to ShareFile, this attempts to read "file://foo.txt" from /, which fails. **Give an example of how this feature would be used** Apps could write files to the private data directory and only make them available to share with other apps when the user elects to share them. **Why doesn't the current App Inventor system address this use case?** Attempting to share a file using a relative name fails because it is computed relative to `/`. We can detect if the file name doesn't begin with `/`, which would result in an error anyway, and instead resolve it relative to the app-private data directory. **Why is this feature beneficial to App Inventor's educational mission?** One could use this as an opportunity to teach about data access/security and privacy in the context of App Inventor.
