UBlueprintPathsLibrary::HasProjectPersistentDownloadDir

function Engine Blueprint Since 4.0

#include "Kismet/BlueprintPathsLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Returns true if a writable directory for downloaded data that persists across play sessions is available on the current platform. Equivalent to FPaths::HasProjectPersistentDownloadDir() exposed for Blueprint/Python.

Caveats & Gotchas

• Always call this before ProjectPersistentDownloadDir() on console/mobile targets — not every platform exposes such a directory, and calling the path getter when this returns false can hand back an unusable or empty path.
• Availability is platform-dependent, not project-dependent, so the result can differ across build targets for the same project.

Signature

static bool HasProjectPersistentDownloadDir();

Return Type

bool

Example

Check before using the persistent download directory C++

if (UBlueprintPathsLibrary::HasProjectPersistentDownloadDir())
{
    FString DownloadDir = UBlueprintPathsLibrary::ProjectPersistentDownloadDir();
    UE_LOG(LogTemp, Log, TEXT("Persistent download dir: %s"), *DownloadDir);
}
