They support the older SysV filesystem, with 1k and 2k blocks, but they introduced the Acer Filesystem a few releases ago. I think its a SysV filesystem with enhancements to the block layout techniques, as well as support for long filenames and symlinks. As for as a I know, its proprietary. I don't recall ever seeing a technical description of the design in print. Things get worse, because they introduced two new filesystems in the new release, the DTFS (Desktop filesystem), which includes compression, and HTFS (High Throughput). One of these includes journaling, I forget which. Once again, I'd be suprised if they weren't proprietary. Robert Sexton
