The Allow Searching of Files Systems Not Fully Supported by Windows setting will allow Identity Finder to search any non-Windows-supported remote file system. Depending on the method used to connect to a system running an operating system other than Microsoft Windows (such as a Mac, Unix, Linux, Mainframe), unsupported file name lengths and/or file name characters may be reported to Windows. In these instances, invalid file names or paths cause instability in Windows and therefore in Identity Finder. By disabling this feature, Identity Finder will only search drives that are fully supported by Windows. If you choose to enable this feature, you can have Identity Finder warn you when it finds a remote drive that is unsupported. To do this, enabled the Display a Warning when Unsupported File Systems are Detected checkbox.
