AzCopy Lastest Version(v8.1) Info is null

[v-tawe]

When use the AzCopy provided in this doc, the script went into below error :

Version of AzCopy found at default install directory is of a lower, unsupported version. Please input the full filePath of the AzCopy.exe that is version 7.0.0.2 or higher, e.g.: C:\Program Files (x86)\Microsoft SDKs\Azure\AzCopy\AzCopy.exe.

and finally find the issue is we cannot access the version info:

PS C:\WINDOWS\system32> $FileItemVersion=(Get-Item 'C:\Program Files (x86)\Microsoft SDKs\Azure\AzCopy\AzCopy.exe').VersionInfo
PS C:\WINDOWS\system32> $FilePath = ("{0}.{1}.{2}.{3}" -f  $FileItemVersion.FileMajorPart,  $FileItemVersion.FileMinorPart,  $FileItemVersion.FileBuildPart,  $FileItemVersion.FilePrivatePart)
PS C:\WINDOWS\system32> [version]$FilePath

AzCopy 8.1.0 is built against .Net Core. There's a known issue in .Net Core's building tool that it doesn't set version info in the exe binary. The version info is set in AzCopy.dll. Is it OK for you to try to get version info from AzCopy.dll?

AzCopy ~7.* doesn't have this issue.

To make the script works before the version issue is fixed, do you mind to change the script by:
change the 2 places of:

if([version] $FilePath -lt "7.0.0.2")

to:

# only netcore version AzCopy.exe has version 0.0.0.0, and all netcore version AzCopy works in this script 
if(([version] $FilePath -lt "7.0.0.2") -and ([version] $FilePath -ne "0.0.0.0"))

I have tested this works on my machine.

I've gone ahead and updated the script with the appropriate change which was included in this ticket.

Accordingly,
