Why SolidWorks File Rename remains unchanged in Cache Folders?

Hi Team,

  • I create a part file and saved it into 3DExperience Platform in name of "Hex_Base".sldprt
  • The cache file have been generated in local cache folder in the same name "Hex_Base".sldprt
  • Then, I renamed the part file as "Hex_AB_Base_01".sldprt in SolidWorks and again saved it into platform. 
  • After the rename, the cache file which generated in local folder remains unchanged. That is still in old name   "Hex_Base".sldprt

Why File Rename is Un-changed in Cache Folders?
