In the old period, DSM never support exFAT because it's a MicroSoft patent file system. But the memory cards for digital cameras over than 32GB (e.g. 64GB, 128GB), the default format is exFAT. If I want to copy data to DSM, that will be a bigger problem.   So from last year I tried to figure out how to support exFAT in DSM 5.0 and finally success. Because DSM is a kind of linux system, so just use the linux exfat packages will be done. Recently, after I tested to install DSM 6.0, also success
