    [ solution ] double click .dem starts dota2 in replay mode

    Hi guys,

    After spending the entire morning looking on internet for a solution to the wierd expansion of steam dota2 launcher from "c:\" to "c : \" (which prevents starting dota with params like +playdemo "c:\mydir\replay.dem"), I made this batch msdos file.
    It creates a symbolic link (to avoid copying large files) of the clicked .dem file to \dota\replay-batch\ with a clean filename and then starts dota with the params required to play it.
    In order to use it, you need to put the following lines in a file, let's say C:\games\replay-dota.bat, change the first line so that dota2 dir match yours, right click a .dem file, "open with"->"choose default program"->browse, pick the file you've created.
    If you have better msdos skills and you know how to improve this, I hope you'll share your thoughts with us.
    Further easy improvements could be:
    - renaming the file or moving to another directory after watching it
    - creating other actions in the windows registry classes, so right click could come up with options like "save this demo to your narcissist collection" to easily copy your last meepo game from \dota\replays to a predefined location.



    :: CHANGE THIS TO YOUR OWN DIR CONTAINING THE dota.exe FILE
    @SET dotadir=C:\GAMES\STEAM\SteamApps\common\dota 2 beta

    :: startup params
    @SET dotaparams=-novid -console +hideconsole
    :: note: +demo_quitafterplayback "1" not working
    :: in case of any unknown params, dota will start normally with no replay

    echo trace: adding replay-batch dir
