Windows XP File Assocation Fixeshttp://
www.dougknox.com/xp/file_assoc.htm
sorry for the late answer, i have tried more than 20 stupid solutions
(and the same number of GHOST imagefile to restore lol) since these
days and now i have found what i want... i can change my file
association in any case
in fact file association under windows XP depends of mime associations
and extension file so to force it to launch what you want they are 3
solutons (not of all can works, i think third works in all case)
1) force path and application filename you want instead of default
file association
ftype IrfanView.mp3="e:\mplayer\mplayer.exe" "%%1"
ftype IrfanView.ogg="e:\mplayer\mplayer.exe" "%%1"
ftype IrfanView.wav="e:\mplayer\mplayer.exe" "%%1"
2) classical assoc and ftype function
assoc .mp4=ztemp1
ftype ztemp1="e:\mplayer\mplayer.exe" "%%1"
3) the registry method, use this hack to simulate "open with"
explorer.exe right click option
