Hi Gerald and others, I have changed the subject to better reflect the topic at hand. The "8sinks" is a tribute to Dean Jackson, a tech support personnel who died in 2006. Since then, HW engineers put this as part of the KeySoft upgrade as a remembrance of him. He was a former moderator on this list who was helpful in many occasions - even staying up some nights to answer our questions - something that some of the users are doing now. The "dj" key from product key prompt is his name initials. The Keysoft system disk (RAM Disk) is composed not only of Windows folder and its branches, but includes files and folders for running the operating system and KeySoft and is a repository of system files such as sounds, printer drivers and so forth. The disk is divided into two parts: the actual RAM content and the accessor to the ROM image files. The Windows folder is what constitutes the ROM image of a Windows CE device (source: Microsoft article on Windows CE file systems), with other folders being the actual RAM content that is allocated on it as though it's a storage device ( that's the definition of a RAM disk). When the BrailleNote runs, it uses this Ram Disk as the temporary location for storing things, such as temp files for Internet, cookies and downloads (well, almost). This is the reason behind some RAM shortage issues (at least storage portion) reported on the mPower platform, and the chief reason why earlier KeySoft versions have file download problem, which is inherent on all CE devices (there was a discussion on other lists about a device downloading only 11 MB of a file, which was reported to the manufacturer). This is also the evidence behind relatively large portion of free space on it even though the disk holds about 4 MB of data (the majority of contents are concentrated on the ROM portion - that is, under Windows folder). It'd be hard to explain how memory allocation works when a program is run - both due to my knowledge at this point (I'm a beginning programmer myself) and the complexity of this information at hand - unless I hope HW engineers would be happy to "reveal" this info themselves. Anyway, hope this helps. Alex or other "developers," do you have anything else to add? Cheers, Joseph
