The Liquid XML Editor can open XML documents of any size so there is not an XML file size limit.
Features are automatically turned on and off depending on the size of the document as follows:
- XML Documents < 10 MB - All features (Syntax Highlighting, Document Outlining, Intellisense) default value = ON.
- XML Documents > 10 MB - Document Outlining default value = OFF.
- XML Documents > 75 MB - Large File Editor is used by default*.
*You can change these value using the menu Tools->Options->Environment->Performance options. Depending on your PCs capabilities, you may be able to set these values much higher.
The Large File Editor can open files of any size (tested to 2GB+) as it pages the data from disk. This restricts the functionality, but still allows you to use the tools Format Document and Validation.
