Hello everybody, i've made a little script that associates every extension known by linux in wine, unless the extension isn't already associated to some other program. So you can doubleclick on a file from winefile and have it opened with the corresponding linux application. It's a quick and dirty script that generates a .reg file, it isn't freedesktop compliant, i am a KDE and only KDE user [Wink] The script reads the global mime database located at /usr/share/mime/globs, merges it with the user database located at /usr/share/mime/globs then generate an extension.reg file. Every extension is associated to a "kdestart.exe" script that you can put somewhere in the PATH and customize as you like (and maybe make it freedesktop.org compliant [Wink] ) Here's the script (copy and paste in a file, make it executable and run it) WINEPREFIX=${WINEPREFIX:-$HOME/.wine} FILEOUT=extension.reg echo REGEDIT4 > $FILEOUT echo >> $FILEOUT for ext in `cat $HOME/.local/share/mime/globs /usr/share/mime/globs | grep "*."|cut -f 2 -d :|sort --unique -f | cut -f 2 -d "*"`; do ext2=`echo $ext|cut -f 2- -d .` esiste=`grep -i '\\[Software\\\\\\\\Classes\\\\\\\\'$ext'\\]' $WINEPREFIX/system.reg | wc -l` if [ $esiste == "0" -a $ext != $ext2 ] ; then echo Aggiungo estensione $ext $ext2 echo "[HKEY_CLASSES_ROOT\\"$ext"]" >> $FILEOUT echo @=\"$ext2.document\" >> $FILEOUT echo "[HKEY_CLASSES_ROOT\\"$ext2".document]" >> $FILEOUT echo @=\"$ext2.document\" >> $FILEOUT echo "[HKEY_CLASSES_ROOT\\"$ext2".document\\shell]" >> $FILEOUT echo "[HKEY_CLASSES_ROOT\\"$ext2".document\\shell\\open]" >> $FILEOUT echo "[HKEY_CLASSES_ROOT\\"$ext2".document\\shell\\open\\command]" >> $FILEOUT echo @=\"C:\\\\windows\\\\command\\\\start.exe kdestart.exe \\\"%1\\\" >> $FILEOUT echo >> $FILEOUT fi done Once run, merge the resulting file to the registry (regedit extension.reg) And here's the kdestart.exe script, put it where it can be found ($HOME/bin or /usr/local/bin) and make it executable #!/bin/bash echo $@ >> $HOME/kdestart.log i=`winepath -u "$@"` echo $@ $i >> $HOME/kdestart.log kfmclient exec "$i" #------------------------------------------------------------------ The last line, i.e. the command used to launch ISN'T freedesktop compliant and can be executed only under KDE. Hope this can be useful to someone.
