Trados Studio 2015 file cannot be opened anymore

Question

I was working on a large project in Trados 2015 – the project consists of approximately 18K segments – and after a while “System out of Memory Exception” error messages started to pop up. Fortunately it did not affect the project since I was able to continue my work after restarting the computer every time the above message occurred (4 times in 2 days).
Today however, a different error message popped up when I clicked on “Save”: “An error occurred while parsing EntityName”. After that I was no more able to open my file or do any other actions with it.
The Hungarian SDL vendor suggested the following possible solutions to no avail:
kb.sdl.com/
producthelp.sdl.com/.../6574.html
I did as I was instructed but the line and position in question – which is by the way the very last position of the last line - does not contain any ampersands.
We also tried deleting settings as an alternative solution, but it did not help either.
Could you suggest any other possible solutions so that I could continue working on this file?
Thank you very much for your help.

Hi Istvan, 
 Try the following steps: 
 1. Open the file in a text editor. 
 2. Search for & 
 3. If the & is not one of the following, delete it! 
 Ampersand: & amp; 
 Single quote: & apos; 
 Greater than: & gt; 
 Less than: & lt; 
 Double quote: & quot; 
 * Note I added spaces after the & so SDL community does not entitize them on this post :) 
 Make sure you back up the file just in case! 
 Having said that, the file might also be corrupt. 
 Does the last line end with <xliff>? If it does'nt then the file is corrupt...

Hi István, Could it be that the file is actually truncated? Can you see this at the end of the file? I've seen this before and in this case (if these are not the last elements in the file) you will probably have to recreate the project and pretranslate from your TM to get back to where you were. But hopefully this won't be the case and the trick from Jesse will help. Regards Paul

Hi István, 
 
The large file would be non-performant, but should not be the cause of the crash. My guess would be that when working with such a large file many things will take longer than normal to complete and if you happen to have external software such as security applications, or disk cleaners running in the background; or maybe you have the files on a separate drive that is impacted by connectivity occasionally then the file could be impacted by one or more of these things, possibly causing it to become truncated. 
 
Perhaps you can check some if these things, or cut the file down into bit sized chunks for the translation and then piece it together again afterwards.
