Does windows lock text files that are being copied?

[DRH192]

Hello all,

I would like to know if windows places a lock on text files that are being copied from a shared network drive? i.e. if john smith starts to copy a file to his local machine at 10:00 am and the file is 20meg and it takes 2 minutes to complete, is the file locked for those two minutes. So if John Doe wanted to copy the same file to his machine at 10:01, would it let him? I don't care if the files are locked against editing as editing will never be required, its just copying the file.

Sounds a really obvious question but wanting to check.

Many Thanks

Pretty sure it doesn't as I've several times had multiple machines copying the same source file from share over the network.

It'll lock any writes (or requests to open the file in write mode) but concurrent reads should be no problem.
