Exporting file query

[Jagtazman]

Ok I am new to this so please bear with me.

 

I exported a easy pop file made amendments and upload all went well

Then I decide to add more products so I exported again

I noticed the file name was the same as before.

Made the change when I uploaded this time went a bit funny

Someone told me a while ago can only use the file once.

So my question is, If I export more than once on the same day and it tries to save exactly the same file name am I ok to change it?

Or is there a bug that needs to be fixed?

 

thanks
