Attachment Size issue of Dataverse

I am using two ways to upload the files into Dataverse as below:

1, Create one file column, used form control to directly submit the file

    Set MaxAttachments is 1(actually this is blocked, default is 1), set MaxAttachmentSize is 30MB, then upload the test file(13MB) , result is successful, I can submit this file to Dataverse file column.


2, Use form attachment control to upload this same test file

   Set MaxAttachments is 6, set MaxAttachmentSize is 30MB, then upload the test file(13MB) , result is failed, I can add this file into the attachment control, but when I enter the submit button, which still spend some time to run, but after that, no files can be found in attachment control, it's empty.


I need to use attachment control, because it can submit multiple files, I tried one file with 3MB, it is OK, but this 13MB file is failed, I don't know what is the hided size limit of Dataverse attachment






attachment control

Hi @BollGary ,

 The default Maximum file size is 32 MB and the largest size you can set is 10 GB. The file size limit can be set individually for each column of file type added to a table. Please check the 'Maximum file size' of the file field.





Best Regards,



Dear Friend,

For file column is ok, I have set the enough Maximum size, and it can work well, the issue is attachment, although I have set the maximum size is 30MB, but it seems only allow below 5MB.
