* The FME Flow System Share files include Repositories and Resources. By default, an Express Installation of FME Flow writes these files to the path specified by the %ALLUSERSPROFILE% environment variable, which defaults to C:\ProgramData\Safe Software\FME Server\. If your Express Installation of FME Flow specified a different directory, or if your FME Flow is a Distributed Installation, then these files are written to the directory specified.

** On an Express installations, this account is created by the FME Flow Installer during installation. On Distributed installations, you must create this account prior to installation. For more information, see Provide a Remote File System for the FME Flow System Share.

*** To ensure the integrity of your overall file system, avoid running the FME Engines under an account with local administrator privileges, unless workspaces read or write data that requires a local installation of Esri ArcGIS. These formats require an administrator account to access the ArcGIS license.
