Import video from files and it imports me a video with the same number but from another file

Hi guys 

I am on editing/ choose from Files to import a video -as an example C005

system brings a video with the same number , BUT from another file and not the one i choose

i need to go out , rename the name of the video and after its ok. 

It's very difficult and it takes time when i have a lot of videos to work with - and usually in have a lot

what do you suggest ;;;

Thank you
