sharepoint online – What is this green box with a white arrow next to the word doc icon?


I was moving folders to a different location in sharepoint, where all the files within the folder moved except for this one.

What is distinct about this file from the others is the green box with a white arrow ned to the word doc icon. Refer to pic.
Icon
This file also seems to be corrupt as i get a Microsoft error “Word ran intoa problem opening this document in a browser. To view this document please open it in the desktop version..”
When I do, It is a blank document.

Does the arrow next to the icon indicate the file is corrupt or?

Any feedback is appreciated. Thanks
