Syntax

bool UnloadPakEntryFilenames
(
    TMap< uint64, FPakEntry > & CrossPakCollisionChecker,
    TArray< FString > * DirectoryRootsToKeep,
    bool bAllowRetries
)

Remarks

Saves memory by hashing the filenames, if possible. After this process, wildcard scanning of pak entries can no longer be performed. Returns TRUE if the process successfully unloaded filenames from this pak

Parameters

Parameter	Description
CrossPakCollisionChecker	A map of hash->fileentry records encountered during filename unloading on other pak files. Used to detect collisions with entries in other pak files.
DirectoryRootsToKeep	An array of strings in wildcard format that specify whole directory structures of filenames to keep in memory for directory iteration to work.
bAllowRetries	If a collision is encountered, change the intial seed and try again a fixed number of times before failing
