For an example:
./content/foo/foo.ann
./content/foo/foo.bmp
./content/foo/foo.dsl or foo.dsl.dz
Now, put all .jpg/.wav/... into a sigle zip file by using a zip tool.
./content/foo/foo.dsl.files.zip
Note:
0. foo.dsl or foo.dsl.dz MUST have sound tags. you could verify at first.
1. foo.dsl.files.zip MUST have not any (level) directory, viz. all files are in same folder and zip them into a NON-Folder zip file.
2. resource file name MUST be XXX.dsl.files.zip, 'XXX' is the dictionary main name.
it's cool.
good luck.
