The assets of your app are read only
Store the data in ASD, i.e. set file scope to App and use filename yourFilename.txt

sigue con el mismo problema al cambiar como se ve en la foto
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

Remove the // and use only the filename.
Also you do not need to delete the file, it just will be overwritten
I do not see you setting the file scope to App...

As already said, set the file scope ro App and remove the double slashes
You are still trying to write to assets, which are read only
http://ai2.appinventor.mit.edu/reference/components/storage.html#File
Below we briefly describe each scope type:
- App: Files will be read from and written to app-specific storage on Android 2.2 and higher. On earlier versions of Android, files will be written to legacy storage.
- Asset: Files will be read from the app assets. It is an error to attempt to write to app assets as they are contained in read-only storage.
