In an FCS installation, files checked into business objects could be duplicated. That is, a copy of the same file could be checked into multiple business objects. The deduplicatefile store command lets business objects within that store share a file. The duplicatefile store command copies a file to each business object in that store that uses it.
Deduplicatefile means that all files checked into business objects in the target store will be shared (duplicate copies removed) by other business objects that use the identical files.
Duplicatefile means that files shared by business objects in the target store will be copied to other business objects that currently share those files.
deduplicatefile store STORE_NAME [lattice LATTICE];
or
duplicatefile store STORE_NAME [lattice LATTICE];
STORE_NAME is the store
LATTICE is the name of a vault
If you specify a lattice, you limit the duplication or deduplication to files in that vault.
