WriteAllBytes OutOfMemory in PowerShell

I have an API which returns a file as byte.
I am trying to download this file onto a local machine using PowerShell (needs to be PowerShell for other automation reasons).
I am using WriteAllBytes, however, it throws error with files which are larger than 100MB (I think, threshold might be different).

byte

WriteAllBytes

Are there any other ways to download these files and convert byte into an actual file?

byte

Here is what I have at the moment:

$fileInfo = New-Object ($namespace + ".fileInfoRequest")
$fileInfo.Filename = "$($File)"
$fileInfo.Hash = "e0d123e5f316bef78bfdf5a008837577" #random hash so ignore this.
$FileDetails = $WebService.GetFileInfo($fileInfo)
if ($FileDetails.Exists -eq "True") {
[IO.File]::WriteAllBytes("$($InstallPath)$($File)", $WebService.GetFileData($FileDetails))
} else {
Write-Host -ForegroundColor Red "File $($File.FileName) could not be found in the system"
}


$WebService.GetFileData($FileDetails) returns the file data in byte so this is the one that I need to manipulate somehow.

$WebService.GetFileData($FileDetails)

WriteAllBytes()

it throws error

I faced the same message right this morning.
Weirdly in my case the problem was triggered only when using a remote powershell session, so I can see affinity with API which can be passing trough network as well.
It happened, in my case, that the same command from a "standard" powershell session opened directly on the server console was not raising the error.

I was able to avoid it by using the following on an admin powershell session on the server console:

set-item wsman:localhostShellMaxMemoryPerShellMB 2048


After that all the remote powershell session stop to give OutOfmemory.
