How to determine if file is in use?

How can I determine if a file is currently in use?

I want to allow various users to upload files via FTP. Meanwhile there will be a php that launches every 10 minutes that will check for new files and import them into the database. I want to make sure that the files have completed downloading.

Thanks,
JNunez

how about inserting the file into your database when the upload starts and then, when the php is called every 10 minutes, comparing filesizes of the file in db and the uploaded file

A reply at another Forum suggested checking the ftp'ed for modification date change and if it's been more than 10 minutes then import it and remove it.

But thanks!
