Re: API to find the size of an entire folder structure?

This solution must be corrected, because the path length may exceed the

field size limit while recursing thru the directories.

Personnaly, i create another cursor to contains the pathnames :

Pathes(pkid i, path m)

When you start a new subdirectory, you insert it in Pathes cursor, and

in each row of Files cursor you put the Pathes.pkid instead of the path.

A simple request can join the pertinent data.

So far so good, it runs faster and takes less working storage.
