File sizes smaller than 300 Megabytes

For editing large documents (file size up to 300 Megabytes), a special memory optimization is implemented on loading such a file so that the total memory allocated for the application is not exceeded.

A temporary buffer file is created on disk so you have to make sure that the available free disk space is at least double the size of the large file that you want to edit. For example, Oxygen XML Developer can load a 200-Megabytes file using a minimum memory setting of 512 Megabytes and at least 400-Megabytes free disk space.

The increase of the maximum size of editable files comes with the following restrictions:

• A file larger than the value of the above option is edited only in Text mode.
• The automatic validation is not available when editing a very large file.
• The XPath filter is disabled in the Find/Replace dialog.
• The bidirectional Unicode support (right-to-left writing) is disabled.

• The option Format and indent the document on open is disabled for non-XML documents. For XML documents, it is done optimizing the memory usage but without respecting the options set in the Format preferences page.

• Less precise localizations for the results of an XPath expression.
