One solution for the "make sure the file is complete problem"
is for the script that is actually doing the file creatation
is to write/create it into a subdirectory of the target folder.
Once the file is closed & complete, the script simply moves
or renames the file into the target directory. This method
"guarentees" that if/when it exists that the file is closed.
Another solution if for an external process to maintain
file which contains the names of files are are complete
and ready for PL/SQL processing.
HTH & YMMV!
