Thanks for reporting this,

I will see what I can do to get better support for large files. There are some 
limitations to the size of the file that can be 
opened however as the control I am using requires the entire file to be read 
into memory at one time. If the file is a code file 
that has highlighting the performance of trying to edit the file once its 
loaded into the editor might also be prohibitive.

I have recently re-written all the low level file handling since the last 
release version and with the latest development version 
was able to open a (130MB, ~1,700,000 lines) test file I made, so this 
situation may already be a *little* better. However it 
did take about 5 minutes for the file to open and Editra ended up using about 
450MB of memory while the file was open. 

So I can look into some other possible causes and limitations could you please 
provide me with the following information.

1) Does the file you tried to open contain very long lines (+1000 characters 
per line)?

2) Type of text in the file (code, plain txt/data)?

3) Do you have Word Wrap turned on in your Preferences?

4) Method of opening the file (command line, Open file dialog, Drag and drop).

5) Amount of memory (RAM) in your computer

Thanks,

Cody Precord

Hi Cody,

here are the answers to your questions:

1) Does the file you tried to open contain very long lines (+1000
characters per line)?

Yes up to about 4000 characters.

2) Type of text in the file (code, plain txt/data)?

It is a log file. Plain text.

3) Do you have Word Wrap turned on in your Preferences?

No.

4) Method of opening the file (command line, Open file dialog, Drag and drop).

Double clicking in the Windows File Explorer -> Open with... 
Same effect with opening the file using the Open file dialog.
But using drag and drop it does behave differently: Editra freezes and does not 
return.

5) Amount of memory (RAM) in your computer

2 GB

Kind regards
Thomas

This should finally be fixed now for the next release version after 0.4.75. 
Initial
testing shows a 10-50x performance improvements.
