Returns a logical
value indicating whether the file exists
or not. In case of dir.exists.adf
the path needs to exist and it needs to be a directory in order
to return TRUE
.

This method will look for a file/directory header, based on its name. If such a header exists, it is assumed that the file exists. The file/directory itself is not checked for validity.
data(adf.example)
## This file exists:
adf.file.exists(adf.example, "df0:mods/mod.intro")
## But it doesn't exist as a directory
dir.exists.adf(adf.example, "df0:mods/mod.intro")
## This file also doesn't:
adf.file.exists(adf.example, "df0:idontexist")
