Sets the upper-limit to the number of drawing file entries that can be kept in the product graphics cache.
| Type: | Integer | 
| Saved in: | Registry | 
| Initial value: | 256 | 
The valid range is from 0 to 65535 files.
When the upper-limit is reached, the oldest file entries in the graphics cache are automatically deleted. Setting this variable to 0 disables caching entirely and deletes any files in the GraphicsCache folder that are currently not in use by an open drawing file.
