-### NEW INPUT SYSTEM SUPPORT

-This plugin supports Unity's new Input System but it requires some manual modifications (if both the legacy and the new input systems are active at the same time, no changes are needed):
-
-- the plugin mustn't be installed as a package, i.e. it must reside inside the *Assets* folder and not the *Packages* folder (it can reside inside a subfolder of Assets like *Assets/Plugins*)
-- if Unity 2019.2.5 or earlier is used, add `ENABLE_INPUT_SYSTEM` compiler directive to **Player Settings/Scripting Define Symbols** (these symbols are platform specific, so if you change the active platform later, you'll have to add the compiler directive again)
-- add `Unity.InputSystem` assembly to **SimpleFileBrowser.Runtime** Assembly Definition File's *Assembly Definition References* list
-- open *SimpleFileBrowserCanvas* prefab, select *EventSystem* child object and replace *StandaloneInputModule* component with *InputSystemUIInputModule* component (or, if your scene(s) already have EventSystem objects, you can delete SimpleFileBrowserCanvas prefab's EventSystem child object)

 `android:requestLegacyExternalStorage` attribute in _AndroidManifest.xml_ grants full access to device's storage on Android 10 but requires you to update your Android SDK to at least **SDK 29**. If this isn't possible for you, you should open *SimpleFileBrowser.aar* with WinRAR or 7-Zip and then remove the `<application ... />` tag from _AndroidManifest.xml_.
