Elements in file gone 2 ! Help

I suggest that you contact Bentley Select to see if there is anything they can do to recover the elements (assuming they were in this file and not referenced) I have searched thru the file and can find nothing. After searching for anything in the file, I did a verify and nothing. No level shows use, No additional Models, no Shared Cell Definitions, no Dimension/Text Styles, no Tag Data, no Multi-Line Styles or any other type of stored data. Range display showed nothing. I searched for any sign of elements in the file. I did find some Line Types that were stored in (written to) the dgn but were not being used. In general there was nothing to bring back (that I could find).
Do you do a Compress (File > Compress) on a regular basis to remove junk from the file? If not you should start. I finally did a Compress and the file size is dramatically changed (162,068KB > 170KB)

If the file was closed before an edit UNDO was done then the elements can not be retrieved.

Once again !!!  SS3  Urgent project  day before deadline  and  the all file is gone 600 mb

when attach some Shared content  - ( add some trees and cars )  Microstation closed and after open the file is empty

- WHY IT"S HAPPEND ?

- HOW CAN BENTLEY RESOLVE THIS PROBLEMS  (  I know i can make a backup  but  i want to have option to recover before last open - Is design history help with this or it goes away too ? )

This is a broken file with nothing inside  - but its show 600 mb  >  http://speedy.sh/TtUqG/UR-MODEL-FINAL.dgn

 

I don't work for Bentley, but I'd be more than willing to take a look for you. And I will, as soon as your GIGANTIC file finishes downloading -- I'm getting "6 hours left" here so I might not even be able to open the file till tomorrow. Apologies.

BTW, I don't know if you've been testing the EAP for the new version of Microstation yet or not - but Bentley is looking for users who have large design files to upload them (for testing purposes only). You seem like you work with huge design files frequently, so I'm sure they'd appreciate your help:

Thanks all for answers and sugestions. Thanks Jan for understand and clear this.

I make this huge file because many of my clients need some stuff there are in 3ds or others.
As you know some of this files ( for example furnitures - have about 50 - 100 mb each )

I see that this file is gone when i add some stuff like tree or cars from Shared content. For example i have 10 and add 11 and now is crash. Maybe it's memory problem , maybe the file i add .

I can try EAP because i have time now for testing but i'm not a select user right now.
Last time i use some SIESTA furniture but can work on this - the file have about 2 GB

Now i have Six Core Processor, and 18 GB of RAM. I don't know if the HD is so slow, or graphic card Nvidia 750TI but this big file once open, once not. And rotate is horrible.

I can help Bentley with this because i always work with big files - and i see that Compress option reduce the size well .

As this seems to keep happening to you and it would seem the same file or type of files  and I think the amount of problems and time lost and grief you've had that I think you should invest in a license  for Axiom tools File Fixer .. I think you can still buy just that  tool and keep paying the annual subscription fee as well as tech support..

I used it a lot in my last job and it pays for itself first time.. especially if you run it over all your  files to prevent future crashes ...

Take a look at their web site www.axiom.com

I think you can even do a try before you buy as well as send them a file and see if they can fix it.. sounds to me like your  files are ticking time bombs waiting to fail..

My main source of problems came from users  ref attaching acad  files and copying in direct from ref acad files data like acad patterns and acad shared cells...then detaching the dwg refs...
