First of all sorry with my really poor english i try to find at this moment in windows ME, but this will work on Windows 98 SE (where i found it!). files modified: folder.htt in Windows directory (where i think this did work!) standard.htt in Windows\Web dir sysroot.htt in Windows\Web dir there is one way, you can have mp3 preview too, just find your hidden files with the .htt extension in the folder X:\Windows\Web or you can type: X:\Windows\Web\standard.htt X:\Windows\folder.htt (recommended) infrom your notepad (you need to replace, X: by your Windows drive example: C:\Windows\Web\standard.htt D:\Windows\Web\standard.htt) i hope it works for you find the section: function IsMovieFile replace: return false with return true if there is not your extension you can ad in the middle just like the others ",avi,asf" in case you can´t seeit you´ll need dowload the codecs n install (that´s the DivX with avi extension) and to add mp3 preview just follow the steps for video preview, there is next to it, replace return false with return true, and add the extension ",mp3" (Windows ME have it already included)without quotes dont get confuse and add it in the middle, im really sure it can be in Windows 98 updated (maybe just with iexplore updated i didn´t try this before, aybe it works without updates), i use this in Windows 98 SE and works perfect, just like opened media player, because have the main control, BW, PLAY, FW, PAUSE, STOP, Volume Control. if you can´t find the file .htt in Windows 98 SE, check this desktop.htt and folder.htt. you should ask why the other files, the reason is: i dont have installed Windows 98 right now, i have windows ME in one pc and windows xp in the second both are slow, 166 MHz and 233 MHz. i found the needed file in windows ME (who thinks is not the same windows 98 n windows me xcluding bugs and easy to use). if, there is a little different with windows 98 SE could find the value "Media: true" or "var media : true" close to the top, i hope to be wrong with these las 2 word lines, but just in case don´t work for the movie preview (and mp3 preview) try to find what i say in this paragraph. note: if don´t works what i say, sorry, try to find by yourself... final note: i was testing, at the end of all: works folder.htt (i found it in Windows dir wich i modified return false with return true, then i made a copy to Windows\Web and it works fine) my proof to my eyes was beck.asf audiofile played in x:\my documents\my music folder. for windows me you can find folder.htt hidden in Windows dir, modify it and copy or move to Windows\Web for windows 98 se try to find folder.htt in Windows\Web dir (in case, only in case you dont get function IsMovieFile in folder.htt found in Windows\Web dir try to find in Windows dir) i almost forgot, youll need to have selected to ake it works, and other application wich works, i think is fotoslate (not really sure but it was from the same company, long time til now i remember that, was cool) from ACDSee when you do right click on an audio or movie file, it starts playing (the movies in a good thumbnail size in the middle of the context menu) have phun! guys it was Maxfutur from México.
