I am trying to open a file larger than 100 MB to edit it in Oxygen XML Developer, but it keeps telling me it runs out of memory (OutOfMemoryError). What can I do?
You should make sure that the minimum limit of document size that enables the support for editing large documents (the value of the option Optimize loading in the Text edit mode for files over) is less than the size of your document. That will enable the optimized support for large documents. If that fails and you still get an Out Of Memory error you should increase the memory available to Oxygen XML Developer.
