Are the DOS findfirst/findnext directory functions deterministic.
That is, will they report the files in the same order for a given
disk?

A related question, is the order the files are retrieved based upon
creation order?  That is, if I create files a, b, c in that order,

Not unless the files are on there in exactly the same order.  You get
the files in the order they are in the directory data blocks themselves.
I am working on a program where I want the files in a more deterministic
way, and I sort them myself.

Depending on the order they are in the directory entry.  Remember that
this can be changed by directory sorting programs such as norton DS,
etc...
