1# Bundle Manager Subsystem Changelog 2 3## cl.bundlemanager.1 Optimized File Quantity Verification in Sharing Scenarios 4 5**Access Level** 6 7Public API 8 9**Reason for Change** 10 11Verification on the number of files is optimized in sharing scenarios. 12 13**Change Impact** 14 15This change is a non-compatible change. 16 17Example:<br> 18An application is configured as follows for receiving files in sharing scenarios: 19 20``` 21{ 22 "utd": "general.image", 23 "maxFileSupported": 3 24} 25```` 26Both JPEG and PNG images are of the general.image type. Assume that two JPEG images and two PNG images are to be shared. 27 28Before change: 29 30Neither the number of JPEG images nor the number of PNG images exceeds the value of **maxFileSupported**. Therefore, the application is displayed on the sharing panel. 31 32After change: 33 34The total number of files of the specified type is verified. Since the total number of images is 4, exceeding the value of **maxFileSupported**, the application is not displayed on the sharing panel. 35 36**Start API Level** 37 3811 39 40**Change Since** 41 42OpenHarmony 5.0.0.53 43 44**Key API/Component Changes** 45 46**maxFileSupported** in [module.json5](https://gitee.com/openharmony/docs/blob/master/en/application-dev/quick-start/module-configuration-file.md#skills). 47 48**Adaptation Guide** 49 50The **maxFileSupported** field specifies the maximum number of files of a specified type that can be received or opened at a time. When an application is on the receiving end of sharing various types of files, it must consider the maximum number of files for each type that it can accept. 51
