What is the folder called /storage/emulated/0/.photoShare/thumb/lcd
.photoShare is a folder used by Huawei devices for it's Cloud service.


If Huawei's Cloud is enabled on your device, your gallery may have been synced to your Huawei's "personal" cloud storage.

You can turn off the cloud backup option for your photos, but maybe you need this service in case of emergency, where you accidentally deleted your pictures, at least you'll be able to restore what was synced before in the cloud service.

It's safe to delete the folder, but doing it from settings will be better to avoid any data loss if you're syncing your folder with the cloud service.
