How can I get the selected files in the File Picker?

[Pasquall]

I try to use File Picker to select files from my system and then upload them to a folder with my form.

I successfully loaded the files into the data variable, but for my next step I need these chosen files to load and I don’t know where they are stored inside File.

When I inspect File I can see: { name, lastModified, lastModifiedDate, webkitRelativePath, size, type }

Where is my File data to upload It?

I found this two links than solved my problem parcially. Finnally I will be do in backEnd code.
