Description

Use resolve than join to compute fullFilePath to handle outputPath correctly if set to an absolute path.
Resolve is checking if a parameter is an absolute path and ignore preceding paths.
Join always concatenate all path parameters which add an base path to the outputPath - that creates a non-existing path if outputPath is already absolute.
