Filemaker *will* allow you to copy and paste into that folder while running, however I would highly advise to stop the filemaker server first to avoid a chance of file corruption.
And if the server is a Mac, be mindful that permissions on pasted database files could come different than those of properly downloaded files.
You may have to apply proper permissions within Get Info window after pasting.
Thank you both. The Server is PC.
I will stop FMserver before pasting.
What issues to upload to the server are you having?
I have the case where it tells me the credentials are not correct even though I can open the admin console with them. It has happened to many times for it to be an issue of a typo. Is your "issue" similar to mine?
Basically I get the 'Invalid Username/Password' message after entering the details in the Upload manager. I am definitely using the correct ones.
There is an issue around Filemaker's handling of SSL certificates.
Take a look at this thread, lots of useful information re fixing it. I was in a huge rush to upload a database and my IT dept. had me in a long queue, hence this post.
Trust it helps!
