游戏中使用了自定义二进制文件,那么这些文件应该放到哪里?

代码如下:

let path_fileName = this.getPath(fileName);

console.log(">>readFile:path_fileName=", path_fileName)

var fileInfo = {

                filePath: wx.env.USER_DATA_PATH + "/assets/1/9900011.bin", //要读取的文件的路径

                encoding: "ArrayBuffer", //string 否 指定读取文件的字符编码

                success : function () { console.log(">>readFile:success") }, //function 否 接口调用成功的回调函数

                fail : function () { console.log(">>readFile:fail") }, //function 否 接口调用失败的回调函数

                complete : function () { console.log(">>readFile:complete") } //function 否 接口调用结束的回调函数

}

//fileInfo.filePath = `${wx.env.USER_DATA_PATH}` + '/assets/1/9900011.bin'

console.log(">>fileInfo.filePath=", fileInfo.filePath)

let fileSystemManager = wx.getFileSystemManager();

fileSystemManager.readFileSync(fileInfo)

console.log(">>readFile:fileInfo=", fileInfo)

9900011.bin 这个自定义的二进制文件 放到哪个目录下?
