It is, and not just for us scripters but also for the engine as well,
with a long list of system calls needed for every file in a list, when
all we want is just one. Almost always more work than is truly needed,
and when the directory contains enough files it can be noticeably slow.
But for now it's all we have, so we use it.
And frankly, if you have enough files in a directly to make a noticeable
difference in LiveCode, you'll find many other aspects of the system are
slower as well. This is why collections with large numbers of files,
like browser caches, separate them by hash values into subfolders. If
you have a really large number of files and are currently storing them
in a single directory, I can share some tips about using hash functions
to put them into subfolders with roughly equal distribution for faster
