It seems that in version 8.0.4 $InputFileName gives complete path to the .m-file. Evaluating << ExampleData/input.m gives $Input is ExampleData/input.m $InputFileName is C:\Program Files\Wolfram Research\Mathematica\8.0\Documentation\English\System\ExampleData\input.m while evaluating FilePrint["ExampleData/input.m"] gives Print["$Input is ",$Input]; Print["$InputFileName is ",$InputFileName];
