/**

* Returns a promise that resolves to the array of dropped files (if a folder is

|
|
* dropped, and browser supports folder parsing - promise resolves to the flat
|
||
|
|
* array of all files in all directories).
|
||
|
|
* Each file has .relativePath prop appended to it (e.g. "/docs/Prague/ticket_from_prague_to_ufa.pdf")
|
||
|
|
* if browser supports it. Otherwise it's undefined.

* @param {Function} logDropError - a function that's called every time some
|
||
|
|
* folder or some file error out (e.g. because of the folder name being too long
|
||
|
|
* on Windows). Notice that resulting promise will always be resolved anyway.
