Is there any way to export the settings, so I can import it in other PC atom like packages, themes, xml etc.
All relevant information is in the
.atom folder. Most package settings will be stored in
config.cson, and any that require a data store should be putting it in
storage/. For syncing packages,
package-sync is useful (and often faster than a file copy handler on account of the many small files you deal with in an NPM dependency tree).
