Definitely much neater without all the long function names.
I would expect move() and copy() to be able to take a file name for the source
and a directory name for the destination, and in this case move/copy the file
to the specified directory.

I'm not sure I'm too keen on using regular expressions for finding files, as
neither Windows or POSIX use these.  POSIX allows

* = any number of any characters
? = any character
[...] = as per regex but using ! instead of ^

Also '/' can be used anywhere in the pattern to match across directories.
For instance */* will return the names of all entries in all directories
directly under the initial directory.

Furthermore any leading . must be matched explicitly.  There is in fact no
pattern that will find *all* files/directories (including . and ..).

Windows is much the same except [...] isn't supported, leading .'s don't get
special treatment and *.* is the same as '*'.  Both / and \ are treated as path
separators, but you can only use wildcards after the last separator (*\* is not
legal, but mypath\* is).

It would be nice if somehow these pattern matching rules could be used,
although it's not clear how.
