This is an OS error
google is your friend.
I also see that this file has been recovered.
Being able to corral damage to files is one of the prime benefits to FileMaker server.
it would behoove you to spend a few mins reading up on corruption...
That's an OS error, not a FM one; probably has to do with how much disk space is allocated to your account (the quota).
Lots of red flags in your description and the screenshot. The fact that the file has the suffix "recovered" is not a good sign for its health.
And if files are being copied while hosted: that would cause the damage to begin with.
What is "share over IP"? Is the file on a network share and people open it from there?
