Hello Evgene, Serhii, and others, I do appreciate your time on my question.
I understand Serhii's answer. However, it s not my question still. Reading my question again, it might not be clear enough. I must recognize.
What I want is not to have a progressbar that count the number of files uploaded (incrementing by one unit each time the success response is received) but
the quantity of bytes fetched up to the Appery's files table out of the total file's weight (progress% = bytesFetched / totalFileBytes).
I m using the Appery's API
uploadMultipleFilesHelper([picUpload_service], Apperyio(['photoInput']));
how can I get those 2 info bytesFetched and totalFileBytes ?
thank you for your time again
Eric
