How do you plan to handle filenames? Currently FilePath is simply a string.
Would it be decoded/encoded automatically? If so there is a nasty catch. Not
all valid filenames have representation as strings. On linux (and I suspect
all unices) file name is sequence of bytes.
For example let consider file with name {0xff} on computer with UTF8 locale.
It's valid and everything, but its name cannot be converted to string. 0xff
byte cannot appear in UTF8 strings.
