I exported my registry which created a large text file - 90+ MB. An attempt to view in the built-in DOpus viewer pane took several minutes to reach 40%. I gave up and killed and restarted DOpus which by then was not responding. Out of curiosity, I tried opening the same 90MB file with..[ol][li]Notepad ~35 secs[/li]
[li]Wordpad - got to 35% then hung[/li]
[li]MS Word ~15 secs to display 1st page then a couple of mins to repaginate all 18,000+ pages[/li]
[li]Notetab Light ~15 secs[/li]
[li]Notetab Pro ~5 secs[/li]
[li]FRHed (Hex editor) ~2 secs[/li][/ol]With the exception of MS Word all those that did not hang opened the complete file in these times.
The Opus text viewer plugin uses a Rich Edit control which is the same underlying control that Wordpad uses - obviously it has an issue with extremely large files.
Up front - I know this is an old thread
Please allow me to 'revive' it - I do not want to steal it, but I intended writing about the same matter, but noticed a previous thread already existed.
It could be that a large file is accidentally selected (having the preview panel open).
In my case Opus crashes. I could not 'halt/stop' the preview process, which I also understand.
However, I don't know whether it is more or less predictable for Opus that it will go beyond a kind of 'threshold' after which Opus is likely to run into problems(?) and therefore warn user to better use an external editor?
Practical scenario may be that in case of viewing files, one can scroll up/down the list, do renaming based on the contents, but then select a file that is too big.
