outdated models cannot be deleted

[heredos]

when trying to save space on my phone, i realized that rwkv chat with no models installed still has 1.5gb of data present, the same size as the rwkv7-g1a 1.5b that was previousely installed, then superseeded by the g1a3 variant.

would it be possible to automatically delete the previous versions or models? or even better, let the users access them?

Thanks for your feedback. Let me implement it.

Actually we already have the logic to delete outdated weights by scanning the name of the file.

  Future<void> removeFilesNotInConfig() async {
    qq;

    const maxSizeBytes = 20 * 1024 * 1024; // 20MB

    final fileInfos = [
      chatWeights.q,
      roleplayWeights.q,
      ttsWeights.q,
      seeWeights.q,
      sudokuWeights.q,
      othelloWeights.q,
    ].expand((e) => e).where((e) => e.available).toList();
    final documentsDir = P.app.documentsDir.q;
    if (documentsDir == null) return;
    final fileSystemEntities = documentsDir.listSync();

    for (final entity in fileSystemEntities) {
      if (entity is! File) continue;
      if (fileInfos.any((e) => entity.path.contains(e.fileName))) continue;

      // 不移除以 .tmp 结尾的文件
      if (entity.path.endsWith('.tmp')) {
        continue;
      }

      // 检查文件大小，只删除大于 20MB 的文件
      final fileSize = await File(entity.path).length();
      if (fileSize <= maxSizeBytes) {
        continue;
      }

      await entity.delete();
      qqw("delete file (size: ${fileSize} bytes): ${entity.path}");
    }
  }

So I don't know how this happened. Can you review your storage, take a screenshot and send me your outdated weights (e.g. rwkv7-g1a 1.5b)?

unfortunately i had already cleared the app data, i really needed thas space.
I tried to downgrade to 2.5.0 and upgrde to the latest version see if I could reproduce it, and what seems the most likely culprit is that something akin to this happened:

partially downloaded 2.9b model with roughly the same size as 1.5b stayed there, and mixed up the two.

it probably deserves another issue though, or maybe a title change

Can you try to delete and re-install the whole app? And let's see if the issue still exists. Thanks.

Also after I click "Clear all app data" button on my android OS (MIUI + xiaomi14). I find that the size of RWKV Chat back to 288MB (from 2.4GB with 2.9B weights installed).

The version of my app is 3.1.5 but it's not the key because auto deletion logic is implemented since 1.x of RWKV Chat app.

Thanks for you patience. Please just delete and re-install the App. Welcome to get back to me.

I'm working on weights management functions in our app. I hope this will be helpful. Weights management feature will be released in 3.5.x of RWKV Chat app.
