Hi,
I'm not able to download large file from Azure Storage Blob container (using SAS ) to C:\Download.
I tried Azure Storage Explorer 1.10.1 / 1.20.0 / 1.20.1 with Windows Server version 2012 R2 / 2019.
I also tried AzCopy.
It is vhd file with size 127 GB.
It runs for about 35 minutes and then fails.
What is wrong with that?
Can you please provide me with a working solution?
Please.
Thank you in advance for your help.

    @SC
    Likely there is some network error which is causing the download to fail. AzCopy includes a resume functionality. You need to find the job that failed and use the resume functionality. Please try the commands outlined here to see if this works for you.

    Hope this helps! Let us know if you are still having issues or need further assistance.

    Log contains "the MD5 hash of the data, as we received it, did not match the expected value, as found in the Blob/File Service. This means that either there is a data integrity error OR another tool has failed to keep the stored hash up to date. When Checking MD5 hash."
    I have to used the parameter "--check-md5 NoCheck" and download was successful.
    It would be good to add this as the option (--check-md5 NoCheck) to Azure Storage Explorer.
    Thanks.
