Hi @MYA ,

Suggest to use SharePoint CSOM library to upload files into SharePoint Library folder if you are using C# code, here is a code snippet for your reference:

using System;  
using System.IO;  
using SP = Microsoft.SharePoint.Client;  
  
namespace CSOM1  
{  
    class ReadItem  
    {  
        static void Main(string[] args)  
        {  
            string SiteUrl = "http://sp2016/sites/dev/";  
            string DocumentLibrary = "UploadLibrary";  
            string FileName = @"C:\testupload.zip";  
            string CustomerFolder = "1564_dsfgsst";  
            string UserName = "TheUserName";  
            string Password = "ThePassword";  
            string Domain = "Contoso2016";  
            UploadFileToSharePoint(SiteUrl, DocumentLibrary, CustomerFolder, FileName, UserName, Password, Domain);  
        }  
        private static void UploadFileToSharePoint(string SiteUrl, string DocLibrary, string ClientSubFolder, string FileName, string Login, string Password, string Domain)  
        {  
            try  
            {  
                using (SP.ClientContext CContext = new SP.ClientContext(SiteUrl))  
                {  
                    CContext.Credentials = new System.Net.NetworkCredential(Login, Password,Domain);  
                    SP.Web web = CContext.Web;  
                    SP.FileCreationInformation newFile = new SP.FileCreationInformation();  
                    byte[] FileContent = System.IO.File.ReadAllBytes(FileName);  
                    newFile.ContentStream = new MemoryStream(FileContent);  
                    newFile.Url = Path.GetFileName(FileName);  
                    SP.List DocumentLibrary = web.Lists.GetByTitle(DocLibrary);  
                    //SP.Folder folder = DocumentLibrary.RootFolder.Folders.GetByUrl(ClientSubFolder);  
                    SP.Folder Clientfolder = DocumentLibrary.RootFolder.Folders.Add(ClientSubFolder);  
                    Clientfolder.Update();  
                    SP.File uploadFile = Clientfolder.Files.Add(newFile);  
  
                    CContext.Load(DocumentLibrary);  
                    CContext.Load(uploadFile);  
                    CContext.ExecuteQuery();  
                    Console.ForegroundColor = ConsoleColor.Green;  
                    Console.WriteLine("The File has been uploaded" + Environment.NewLine + "FileUrl -->" + SiteUrl + "/" + DocLibrary + "/" + ClientSubFolder + "/" + Path.GetFileName(FileName));  
                }  
  
                #endregion  
            }  
            catch (Exception exp)  
            {  
                Console.ForegroundColor = ConsoleColor.Red;  
                Console.WriteLine(exp.Message + Environment.NewLine + exp.StackTrace);  
            }  
            finally  
            {  
                Console.ReadLine();  
            }  
        }  
    }  
}  

Thanks
Best Regards
