Losing DGN file when sending it from browser

Hi,

We are sending DGN file from a browser. When DGN file is open in MicroStation and it is being sent via browser at the same time, mostly DGN file disappears (deleted) and DGNxxxxx.tmp file is created. After exiting MicroStation, when you manually rename DGNxxxxx.tmp as DGN file, it works fine.

Why DGNxxxxx.tmp file is created?

Why original DGN file is deleted?

DGN file is still open during sending it by browser. Sending process may take several minutes according to upload speed.

I think MicroStation wants to autosave DGN file during upload process. Because two applications wants to use same file at the same time, MicroStation fails to update it.

How can we fix this collision?
