I see that Aspell is not portable - in either the PortableApps or native version of NP++
DSpellCheck is a different spell checker.
DSpellCheck is portable in both the native and PortableApps version of NP++ - but it’s not as good of a spell checker
. . . Keep DSpellCheck installed, as a backup, portable spell checker
Can Aspell be made portable?
Is there another spell checker like Aspell that is portable?
