About Erasing Objects in Memory and Deleting Files
Erasing Objects in Memory
An object is a file you create in Creo Direct. Every time you save an object, you create a new version of the object and write it to the disk. Each version of the object is stored in a sequence, for example, box.sec.1, box.sec.2,box.sec.3.
When you close a window using the Close Window command, the object is no longer displayed but it remains in memory during the current session. Erasing an object removes it from memory but not from disk.
 
You cannot erase objects when other assemblies that are referencing them are still active.
Erasing an object does not necessarily erase from memory those objects to which it refers, for example, erasing an assembly does not necessarily erase its components.
Deleting Objects
Every time you save an object, you create a new version of the object in memory, and write the previous version to disk. Each version of an object storage file is numbered consecutively, for example, box.sec.1, box.sec.2,box.sec.3.
You can use the Delete command to free up disk space and remove old, unnecessary versions of objects:
