Are large zip files restricted from upload to Blob Storage?

Question

Are large zip files restricted from upload to Blob Storage?

Paul Richards 0

When uploading a somewhat large zip file (6GB) to an Azure Blob store using either the portal or the Azure Storage Explorer the upload fails within a few seconds. If I import a small zip file it works fine or if I change the file extension to something else like *.abc then the upload is successful. After I upload the *.abc file I can then rename it to *.zip and that works fine. Seems like the combination of being a large *.zip file is being restricted for some reason that I can't find reference to.

Hello @Paul Richards ,

There are no restrictions for the zip file. I just tested locally by uploading .zip file of more than 7. GB and it went through successfully.

I used default block size of 4 MiB , you can try using:

You can also try using: azcopy - https://learn.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-v10

azcopy copy "C:\pathtolarge\file.zip" "https://mystorageaccount.blob.core.windows.net/mycontainer/largefile.zip" --block-size-mb 1024 --put-md5

Regards,

Shiva.
