I am in front of a problem using some limitation of Microsoft Power Automate, I have a flow that need to copy one file at a moment and sometime I have file that are more than 100mb and Power Automate doesn't accept http request larger than 100mb.

I am using the classical get_version then get_object. Is there another way to download "large" files from B360 ?

Thanks !

Issue from PowerAutomate

GET Object provides a header Range that allows you to download file by chunk. One demo call is available with the help document:

curl -v 
"https://developer.api.autodesk.com/oss/v2/buckets/apptestbucket/objects/test.txt"
 -X GET
 -H "Authorization: Bearer ShiAeQ67rdNSfmyEmtGW8Lnrcqto"
 -H "Range: bytes=44-83"

My colleague Bryan produced a blog on download manifest by chunk. It follows the similar header. The blog demos how to use this header in code. https://forge.autodesk.com/blog/download-large-derivatives-chunks

  • @Liang I understand the part to request the file in part but I don't find something to regroup these part into one file. – Simon Terroitin Jun 15 '20 at 14:13
  • Simon, this will be a general topic of merging file with chunks. e.g. this post talks about how to merge by PHP, :https://stackoverflow.com/questions/14205445/how-to-merge-chunks-of-file-result-of-html5-chunking-into-one-file-fast-and-ef and another one is by .NET https://stackoverflow.com/questions/27624656/efficiently-merge-file-chunks – Xiaodong Liang Jun 18 '20 at 10:50
