## Remarks
  
Note, this method does not create a file with generated name. It just returns a name of the file which is guarantied unique in the public cache folder. You should create this file manually.
 
To get a full physical path to the public cache, use the [GetAbsolutePublicCachePath(String)](https://www.graphicsmill.com/docs/gmwc/M_Aurigma_GraphicsMill_AjaxControls_FileCache_GetAbsolutePublicCachePath_1_bb3a7a4f.htm.md) method. If you need to get an URL to this file (so that this file could be loaded into the browser), use the [GetRelativePublicCachePath(String)](https://www.graphicsmill.com/docs/gmwc/M_Aurigma_GraphicsMill_AjaxControls_FileCache_GetRelativePublicCachePath_1_bb3a7a4f.htm.md) method.
