How To Export A Windows Registry File Using Java

Question

How can one export and import a .reg file which contains all keys and subfolders just like the registry editor export function?

I've seen various suggestions and libraries eg here .

They only read / write keys by name which doesn't help with many or varying entries. Can it be done using the jna library ?

Answer 1

You could have it kick off a batch file as indicated here .

set rkey=HKEY_CURRENT_USER\Control Panel\Mouse
REG EXPORT "%rkey%" "C:\keys.reg"
REG IMPORT "%rkey%" newkeys.reg
