尝试实现 ximu3#48 在获取数据路径时，检查可执行文件路径下是否有名为 portable 的文件夹，有且有权限写入，则将数据路径替换为此文件夹 潜在问题： - 每次申请路径都要检查一遍，效率低下 - fse.accessSync 貌似没起作用，只检查了文件夹有无，没法检查权限 - Program Files的文件要管理员权限写入，所以不能在这个路径下启用便携模式（除非以管理员启动）
|
便携模式迟迟没更新出来的原因主要是因为目前electron-builder打包出来的更新程序是全覆盖更新，如果数据库在根目录下会导致更新后数据库丢失。 |
抛砖引玉，目前我能想出的解决方案是写一个更新脚本，在用户更新时先判断是否为便携模式，如果是就把数据库转移到temp中，更新完再转移回去。 |
|
感觉便携模式就用不着setup来安装，一般都是直接解压的，考虑打包个zip的？ |
这样的话更新会很不方便，就不能在软件内自动更新了。 |
|
便携模式，理论上拷到其他设备上要能直接用 |
|
如果不需要自动更新的话，那这个实现思路挺好的，我先合并，然后抽空再完善一下，目前更新需求有点多，可能会晚一些。 |
看了下代码，文件IO有点多，会影响性能，可能还是得调整下。 |
是，应该只判断一次的，但没想到好的实现 观察了一下没有注册表update的行为，直接没有确认地给我装到Program Files去了 |

尝试实现 #48
自己十分需要这个功能，就摸索着写来看，第一次写，感觉实现很差
