Another addition of JEA in Windows PowerShell is the user drive. Even if the filesystem provider is not visible to the user, it is possible to map each connecting user a personal drive. It is possible to copy data to and from the personal drive, to, for example, use it as input for a cmdlet:

# The user drive
$sessionConfigurationOptions = @{
    Path = '.SessionConfig.pssc'
    SessionType = 'RestrictedRemoteServer'
    TranscriptDirectory = 'C:Transcripts'
    RunAsVirtualAccount = $true
    LanguageMode = 'ConstrainedLanguage'
    MountUserDrive = $true
    UserDriveMaximumSize = 50MB
}

New-PSSessionConfigurationFile @sessionConfigurationOptions
Register-PSSessionConfiguration -Name WithUserDrive -Path .SessionConfig.pssc

# Copying files simply works.
# Working with Cmdlets like Set-Content requires a wrapper function
$session = New-PSSession -ComputerName localhost -ConfigurationName WithUserDrive
'it just works' | Set-Content .JeaTest.file
Copy-Item -ToSession $session -Path .JeaTest.file -Destination user:JeaTest.file
Copy-Item -FromSession $session -Path user:JeaTest.file -Destination .JeaTestFromConstrainedSession.file

The user drives are located at $env:LOCALAPPDATAMicrosoftWindowsPowerShellDriveRootsDOMAIN_USER, and all files are stored plainly on disk. Keep this in mind when handling sensitive data:
