在flashfxp.exe同目录下放置一个名为 flashfxp.portable 的文件(字节不限)，即可让flashfxp只使用当前的目录存储数据，而彻底不写注册表；官方portable版亦为此法。
This file forces the FlashFXP install to run as a portable install. In function
this is the same as running FlashFXP with the command line flag -portable.
Just delete this file to be able to run FlashFXP in normal mode. Portable mode is
designed to ignore registry entries and only use the FlashFXP data folders found
within the same folder as the flashfxp.exe file. Normal mode will attempt to use
the computers registry entries to locate the data files including license key and
may also create new registry keys.
同理之ftprush portable：在 ftprush.exe 同目录建一个名为 ftprush.ini 的文件，内容如下：
[LICENSE]
PortableData=1
PortableKey=,xxxx-xxxx
xxxx-xxxx为注册码
