 By default Windows systems support the SFN format so whenever a file is created using a long file name (LFN) Windows will create a unique SFN alias for the file. Therefore it should not matter where POPFile is installed. However on some systems this SFN support may have been disabled therefore the 0.22.2 (or later) installer checks for SFN support and will display a message like this if it has been disabled: By default Windows systems support the SFN format so whenever a file is created using a long file name (LFN) Windows will create a unique SFN alias for the file.

 There is a small overhead involved in generating these SFN aliases on NTFS-based systems but if there are folders containing a large number of files with similar names this overhead can become significant so many Windows tweaking/speedup utilities will disable SFN support. For most Windows software this causes no problems, but it can have a negative impact on some software (mostly older programs). There is a small overhead involved in generating these SFN aliases on NTFS-based systems but if there are folders containing a large number of files with similar names this overhead can become significant so many Windows tweaking/speedup utilities will disable SFN support.
