i am not an expert in coding.. kindly someone will explain me in details that how to modify script values ?

and i have a questions,

• can we use this google drive as FTP alternate? if yes, pleaser refer me to the solution.

What should I do now? with UiApp?

What should I do now? with UiApp?

Never mind... I just delete it, and edit some little then it's worked! 😅

why not use just UrlFetchApp?
like?
function uploadFileFromUrl(url) {
var folderID = "jhguguytel3i72t4ldutg3u"; // your Folder ID
var folder = DriveApp.getFolderById(folderID);
var httpoptions = {
method:"get",
muteHttpExceptions:true
};
var resp = UrlFetchApp.fetch(url,httpoptions);
var head = resp.getAllHeaders();
if (resp.getResponseCode()==200)
if (head["Content-Length"] >"0") {
var pic = resp.getBlob().setName(nome+"-"+lattesid)
folder.createFile(pic);
}
}

// ao final vc estrava chamando a VAR "pasta" que não existia... troquei para Folder.
// Ao novatos como eu.... lembrar de definir também "Nome" e "LattesID"
// MARAVILHOSO O CÓDIGO !
// Agora vou tentar colocar ele num loop.... vamos que vamos :D

@X7md May I know how you fix that, please?

For whoever comes to this Gist in the future: I haven't used this code in over five years, and it's unlikely I'm gonna use it again. The UiApp has been deprecated (Thankfully! That thing was annoying to use.), and I have no intention of rewriting this code using HtmlService. In fact, I have no intention of using this code ever again, as I don't think I have the need for it anymore.

(A little bit of history: back then, I had terrible Internet connection, so downloading stuff directly to Google Drive was significantly faster than downloading first to my computer and then uploading. Nowadays my Internet connection is fast and reliable, and I have little to no reason to download anything directly to Google Drive. Additionally, silently truncating the file to 10MB is inconvenient.)

Feel free to use this code as a basis for your own version, and even post a comment here pointing to your fixed/updated version. Have fun writing your own version!
