A compiled object cache is the location where LabVIEW stores the compiled code for certain types of files. You do not need to interact with the object cache, but you can clear it periodically.

LabVIEW stores the following types of files in the compiled object cache:

The object caches are located in the LabVIEW Data directory. The default location of LabVIEW Data on Windows systems is C:\Users\<username>\Documents\LabVIEW Data. You can check or change where LabVIEW Data resides on a system with Tools » Options... » Paths » Default Data Directory.

Clearing the Compiled Object Cache

You do not need to manually interact with the object cache, but you might want to clear the object cache if you delete a large number of VIs that LabVIEW has added to the cache.

When you delete a VI that LabVIEW compiled into the cache, LabVIEW does not delete the associated compiled code. To reclaim disk space that the compiled code of deleted VIs occupies, you can clear the compiled object cache.

Notice You must delete a compiled object cache in its entirety. After you clear an object cache, LabVIEW must recompile each file that had compiled code in the object cache. This recompilation occurs the next time LabVIEW loads each file. Consider this performance tradeoff before clearing an object cache.

To clear the compiled object cache, complete the following steps.

  1. Select Tools » Advanced » Clear Compiled Object Cache....
    The Clear Compiled Object Cache dialog box appears. This dialog displays the different object caches that you can clear and their size on disk.
  2. Select the compiled object caches to delete and click Clear.
    You can Ctrl+click or Shift+click to select multiple caches.
