Backup File delete LG Phone

[Savannahangel]

Okay, so my knowledge of technology is minimal. I could really use some help here. I recently switched to an LG Stylo 3. Originally, I tried to transfer data wirelessly from my old phone to my new phone. The transfer never completed due to lack of space. I chose the option to keep the info that did transfer. I then switched my SD card to my new phone and decided to just keep the new phone as is. I use the ES File Explorer app and noticed there was a large file named LGBackup_wifi.ibf in my internal storage dated from the day I tried to transfer. It takes up a huge amount of space. I was wondering if this file is the transfer I attempted and would like to know if I can delete this. I'm too afraid to just do so. That I may really mess something up. This file is located in both my internal storage and my SD card. Any help would be greatly appreciated.
