Fixing Invalid LAS Files

An LAS file that cannot be found on disk is termed invalid and will display an exclamation point, "!", beside the file. After saving the LAS Layer to disk, a file can become invalid when an LAS file is deleted or moved to another directory. An invalid file can be fixed by selecting a new file or selecting a new folder that now contains the file(s).
