Before this point, it was actually untested by a human and a real device. - On new device detection, now we're auto-adding it to the volume selector. On disconnection, removing it. It's very smooth now. - Listing directories too. But copy and other commands haven't been tested. --- apps/desktop/src-tauri/src/commands/mtp.rs | 25 +- apps/desktop/src-tauri/src/mtp/connection.rs | 127 ++++++---- apps/desktop/src-tauri/src/mtp/discovery.rs | 82 ++++++- .../lib/file-explorer/DualPaneExplorer.svelte | 36 +++ .../src/lib/file-explorer/FilePane.svelte | 223 +++++++++++++++++- .../lib/file-explorer/VolumeBreadcrumb.svelte | 30 ++- apps/desktop/src/lib/logger.ts | 1 + apps/desktop/src/lib/mtp/MtpBrowser.svelte | 169 ++++++++++++- apps/desktop/src/lib/mtp/mtp-store.svelte.ts | 12 +- apps/desktop/src/routes/(main)/+layout.svelte | 51 ++-- 10 files changed, 665 insertions(+), 91 deletions(-) diff --git a/apps/desktop/src-tauri/src/commands/mtp.rs b/apps/desktop/src-tauri/src/commands/mtp.rs index ffec2b3..35e2ef5 100644 --- a/apps/desktop/src-tauri/src/commands/mtp.rs +++ b/apps/desktop/src-tauri/src/commands/mtp.rs @@ -1,5 +1,6 @@ //!
