Hi Netfolx, I got this program from a German friend of mine which in turn had downloaded it from some BBS. It has no documentation with it, but I've used if for a week or so, and what it seems to do is this: - speed-up FAT searching (at least 2 times) - cache all (well...) directories ever read. - (maybe) fix the 40 folder bug It seems to do lot more, I've heard rumours about extra GEM functions, bug-patches etc.etc.... Could some kind soul please disassemble it and find out? (Oh no, *NOT* me!) PS: Oh yes, put it in the /AUTO folder! (You knew that, didn't you?) ------------------ I am impressed with TurboDOS even when used with a floppy disk drive... try deleting lots of files - very fast! However, I would suggest if you distribute it do so with a disclaimer... just in case it trashes the software on someone's hard disk drive. I have NOT tested TURBODOS with a SUpra hard drive unit. ------------------------- - speed-up FAT searching (at least 2 times) - cache all (well...) directories ever read. - raise the 40 folder bug limit to 100 folders (I think) It seems to do lot more, I've heard rumours about extra GEM functions, bug-patches etc.etc.... The main problems with it is that it employs write behind caching so that writes to a disk do not always take place. This is not normally a problem except for floppy disks where it is possible for turbodos to delay writing the FAT tables, when you then change floppy disk it can then write the FAT tables to the new disk thus effectivly trashing your floppy. This is not a problem with hard disk drives though. Turbodos appears to write the entire cache out to floppy when you leave a program and so desktop copies onto floppys do not appear to be affected by the above problems. Turbodos does not run with all software, especially software that does its own internal caching (eg: Laser C) but it does run with the majority of software. Trubodos works with Atari and Supra hard disks but probabally not any other make of hard disk (eg: it definitely does not work with Triangle triangle hard disks). ------------------
