filecopy.cache (collection.cfg setting)
This option allows to enable or disable using the live view as a cache to get files from. When enabled, unchanged files since the last crawl will be fetched from the live view, instead of being copied from the filecopy.source and filtered again.
This will save time in copying and filtering files and is a form of incremental gathering. This option does not normally need to be changed by an administrator.
If you do not want data copied from a cache i.e. you want to ensure that all data is copied from the original source, you can set this value to empty e.g.
This will have the effect of turning off incremental file copying.
