python - Need a way to determine if a file is done being written to -

I am the situation - this is the process that is writing a file, sometimes the file is large 400 - 500 MB I have to know when it's written. How can I fix this? If I look in the directory I will see it there, but it can not be written. Apart from this, it should be removed - as it is on the same internal LAN but not on the same computer and generally the process wants to know when files are written, running the file running on the Linux box with the running process Having the file itself on a window box No samba is an option Xmlrpc is an option for that service on the window box, as well as using SNAP to check that it is viable.

Ideally

• Works on Linux or Windows - which means the solution is OS free
• Work for any type of file Does.

Good enough:

• Works only on windows but can be done through some libraries or

The current best idea is that from time to time the file is open in question by some process in the Windows box and the last to check the PDF and tag View the bytes and accounting for the EOL difference because the file can be created on Linux or Windows.

Most likely you can take several methods, I will try to open the file with the use of writing If this is successful, then no one else writes that file.

Build a web service around this concept if you do not have direct access to files between machines.
