The exfat specification specifies an invalid character set, but there are no restrictions on the use of leading or trailing white-space or dots. Even if the filename has trailing-dot as shown below, it conforms to the exfat specification and can be created on Windows. "a" "a." "a.." These are treated as "a" in the current implementation of linix-exfat, so the intended file cannot be accessed. The specified filename should not be modified to comply with the exfat specification. Therefore, exfat_striptail_len() should not be used. Note: Windows explorer removes trailing white-space and dots, but not the behavior of the filesystem. Also, you can create a trailing-dot filename by quoting it on the command line. BR T.Kohada
