If a file is being generated and you try to open it whilst it is still being
written to disk, does the program trying to access the file damage the file
in any way? (example, I'm generating a large video file and occasionally I'm
not sure if its crashed or finished and so try to open and view the file)?
NTFS or FAT32

Thanks.
 
This depends entirely on the application.

A well-written application will allow only such access as is
appropriate for the current operation. If the condition of the
file is undefined then the application should allow no access
at all. If the condition of the file is defined then read-access
may be permissible.

Some applications allow multiple read/write opens even
when they should not. Notepad.exe is one of them.

In summary: You will have to find out for yourself if you
can safely open your video file.
