  2. Share the image screenshot of file status in Network path with chunk and failed error message and.
  3. Whether fail gets saved successfully and then facing issue in opening the file.
  4. Demonstrate the reported issue with a video and replication procedure.
  5. Whether using Server side or client side Blazor application along with don net version 3.1 or 5.0.

Hi Thanks for providing support. But as per your sample Small files using UploadFiles are not appeared in any folder.
SO I want the method that for large file use chunkFile and for small file used the UploadFiles
Can you please provide any sample on as this sample is only for chunk file but I want the combine for both.
Also it's good if you used async method for it and In SfUploader set AllowMultiple=true.

Hi Karan, 

Thanks for the update. 

Query1: So I want the method that for large file use chunkFile and for small file used the UploadFiles. 

We would like to know you that when the file size is smaller than the chunk size, then it is considered as a default Uploader component. So here in controller you have to write both for Chunk upload and Default upload. We have prepared sample as per your requirement and attached below for you reference. 

public async Task Save(IList<IFormFile> chunkFile, IList<IFormFile> UploadFiles) 
        { 
            long size = 0; 
            try 
            { 
                foreach (var file in chunkFile) 
                { 
                    var filename = ContentDispositionHeaderValue 
                                            .Parse(file.ContentDisposition) 
                                            .FileName 
                                            .Trim('"'); 
                    filename = hostingEnv.ContentRootPath + $@"\{filename}"; 
                    size += file.Length; 
                    if (!System.IO.File.Exists(filename)) 
                    { 
                        using (FileStream fs = System.IO.File.Create(filename)) 
                        { 
                            file.CopyTo(fs); 
                            fs.Flush(); 
                        } 
                    } 
                    else 
                    { 
                        using (FileStream fs = System.IO.File.Open(filename, FileMode.Append)) 
                        { 
                            file.CopyTo(fs); 
                            fs.Flush(); 
                        } 
                    } 
                } 
            } 
            catch (Exception e) 
            { 
                Response.Clear(); 
                Response.StatusCode = 204; 
                Response.HttpContext.Features.Get<IHttpResponseFeature>().ReasonPhrase = "File failed to upload"; 
                Response.HttpContext.Features.Get<IHttpResponseFeature>().ReasonPhrase = e.Message; 
            } 
            try 
            { 
                foreach (var file in UploadFiles) 
                { 
                    var filename = ContentDispositionHeaderValue 
                            .Parse(file.ContentDisposition) 
                            .FileName 
                            .Trim('"'); 
                    filename = hostingEnv.ContentRootPath + $@"\{filename}"; 
                    size += (int)file.Length; 
                    if (!System.IO.File.Exists(filename)) 
                    { 
                        using (FileStream fs = System.IO.File.Create(filename)) 
                        { 
                            file.CopyTo(fs); 
                            fs.Flush(); 
                        } 
                    } 
                } 
            } 
            catch (Exception e) 
            { 
                Response.Clear(); 
                Response.StatusCode = 204; 
                Response.HttpContext.Features.Get<IHttpResponseFeature>().ReasonPhrase = "File failed to upload"; 
                Response.HttpContext.Features.Get<IHttpResponseFeature>().ReasonPhrase = e.Message; 
            } 
        } 


Query2: In SfUploader set AllowMultiple=true. 
 
By default AllowMultiple property is true in Uploader component. So, it is not necessary to enable this property in component. 

Kindly check with the above sample. Please get back us if you need further assistance.
