  Hi @zsanhong,

  Files that uploaded with File Management module can't be downloaded directly by a link for now. We've added "token validation" for extra security.

  First, the UI makes a request to the backend application to take token, that token will be used for download, Example:

  File name: myfile.zip UI makes a request -> // api/file-management/get-token Token = 12345 UI opens a new tab with the url -> api/file-management/[MY-FILE-ID]?token=12345 Then the download process will start.

  Tokens become expired when they used once. So, for each download request, you need to consume new token.

  So, how you can achieve your request, let me show you one example.

  You may create unique tokens for each dowload request by overriding DownloadAsync method of FileDescriptorController controller:

  Note that, you need to secure your api yourself.

  [HttpGet]
          [Route("download/{id}")]
          [AllowAnonymous]
          public virtual async Task<IRemoteStreamContent> DownloadAsync(Guid id, string token)
          {
              var fileDescriptor = await FileDescriptorAppService.GetAsync(id);
              
              // add this
              if(string.IsNullOrWhiteSpace(token))
              {
                  token = await FileDescriptorAppService.GetDownloadTokenAsync(id); 
              }
              
              Response.Headers.Add("Content-Disposition", $"attachment;filename=\"{fileDescriptor.Name}\"");
              Response.Headers.Add("Accept-Ranges", "bytes");
              Response.ContentType = fileDescriptor.MimeType;
  
              return await FileDescriptorAppService.DownloadAsync(id, token);
          }

  Hi,

  There is no any option about file sizes in ABP Framework or related modules.

  You may research for online. ABP Framework and File Management module use the default settings of ASP.NET.
