Summary
If a package to be deployed contains a file path longer than 256 characters, it will end up with an error "Download failure: The filename or extension is too long" when the package being deployed.
Discussion
The file path consists of <serverDNSname>\ManageSoftDL$\Packages\<PackagePath>\<PathInMSISourceFolderIfApplicable>
This is due to the limitation of Windows OS.
Workaround
If the internal folder structure for the package can't be restructured and shortened, the customer will need to see if there is possibility to shorten the <erverDNSname> part or <PackagePath> part to bring the whole file path length under 256 characters.
