Sorry for the basic question, but i instaled this extension and i didn’t find how to “save” the data to the list, i mean, a substitute to “appendToFile”.
May be the function: “copy, fromfilename, to filename”?
I correctly understand that you save the files in a directory and then want all the file names from this directory to show you the List Picker? If yes, then in this extension there must be a “call.FileList” block, by means of which it can be done.
But you can save file names in local storage (as a string with delimiters). In this case, you need to get this line from the repository, make a list from it and assign a List Picker.
Which option suits you best?
The first option seens to be more easy… and yes, you understand correctly, i want to show the file names in the listpicker
I didn’t find this “call.FileList block”, the more closest is the block: “call taifunFile1.DirectoryList.directoryName” i try to use, but didn’t work , but maybe i didn’t use correctly.
I’ll now look at this extension.
I have such a block.
I have this block too…
But how i complete the block?
On the directoryName i put “global data”?
On extension, i don’t now 
On include subdirectories, i supose that i have to put “false”, right?
I did some research…
On directory i put “/storage/emulated/0/AppInventor/data”
On extension i put “.txt”
On include i put “false”
But the listpicker doesn’t show nothing
I’m almost there lol!
I succeed to show the filenames using “*” on the extension, but they show all data, and show all the path, like “storage/emulated/0/AppInventor/data/filename”
What’s the extension of this files saved by “file component”?
Or how can i take away all the path and show only the “filename”?..Maybe using "replace all text, to “0” "?
To display the file name, find position the last character / and select the text after that character to the end of the path string.
