After installing boot2docker under win7, I went into the virtual machine and downloaded the files and put them in the /home/docker directory. After restarting the virtual machine, all the files were lost. It seems that the environment of the virtual machine has been reset after restarting. How can I solve this problem?
Boot2docker is equivalent to a virtual machine and will have a directory shared with the native windows environment. I remember that my default is in Administrator and the default should be under the windows user directory. If you put the files that need to be saved in this directory, they will not be lost.
