Maximum File Size

If you have Document.LexicalParsingEnabled = false along with SemanticParsingEnabled = false and outlining off, SyntaxEditor should be able to handle pretty large files however you of course will lose syntax highlighting and other features. The core editing features will still be there so that it will perform like an enhanced textbox with all the nice commands found in VS.

SyntaxEditor is limited by memory and there is a Large File Handling topic that explains how best to configure it for large files, by turning off various features like what is described above. However we have not tested it with GB-sized files at all.

Thanks for the information.

What is the largest files that you have previously tested SyntaxEditor with?

Any chance that you'll be testing with GB-sized files any time soon?

Probably 100MB or so with the options turned off that are mentioned in that help topic. We're not really gearing SyntaxEditor to edit GB-sized files but it may be able to handle those if you turn those options off.

Since performance is often subjective and can widely vary based on systems, your best bet is to use the evaluation to try file sizes out yourself and see if the performance is satisfactory for you. And use that to determine if SyntaxEditor is the right match for your product.
