you should be able to do what you want with the "add multiple items to end" functionality. you'll just need to maintain the array of items separately from the tree and whenever an update to the tree is necessary you'll first modify the array of items and then delete everything in the tree and reapply the item array. you don't need to know the parent/child tags to use the functionality, you can simply indent the items properly and then use the output from the method to map the tag labview spits back to the original item in the array (see "child two" in screenshot). also, once you populate the tree and map the tags back to the original item array, you can then do incremental updates to it if you want using the single insertion and deletion methods. if this works out for you, please reply back to the forum with the stats (number of files, time consumed, amount of memory used, etc.) of the old vs. the improved method.
