Get file list from Windows directory in background

Our SAP server is currently on a Linux server but migrating to Windows. Our PI servers are on Windows. Everything is running fine except when we are trying to run jobs that require to get a filelist from directory located on a server which is based on Windows.

All FM running in background on Linux will use Unix file patterns and fail on the CALL.

Although this is temporary, I thought SAP would allow this as mixed platforms exist especially during migration.

Anybody encountered that and found a solution?
