Martin - SSTOOLS.INI is a parameter/initialization file used by Fractint and the Windoze version, Winfract. A skeleton version is installed by default, but you can edit/modify it in any text editor like notepad. It can be quite usefull. At the DOS prompt, type: FRACTINT MAKEDOC and hit ENTER key. You will create a 600K DOC file that can be read in any text editor or word program. It can be a bit overwhelming at first, but in it is everything, and I mean everything, you ever wanted to know about Fractint. It will also tell you all you need to know about sstools.ini. Here is one of mine: [Fractint] Passes=1 ;drawing method, slowest but most accurate Corners= ;forces corners definition instead of center-mag FillColor=0 ; Float=Yes ;forces floating point calculation - most accurate Inside=0 ;lake color algorithm - black Outside=Iter ;colors as function of iteration Maxiter=2110000000 ;maximum iterations. best image, but takes longer Video=F3 ;video mode from fractint.cfg file Map=MDMA ;color map used LogMap=2 ;coloring algorithm best for deep zooms Savename=x000.gif ;name of gif file if you save it Sound=Off ;no sound when picture finishes Have Fun JoTz
