check if fille is full

I can not check if the file is empty. Is there anyone who can me?



What file or type of file do you want to check?  



Your question is unclear.  

 Are all your blocks in your project gone?

Or, are you testing to see if a file has any text in it?

Or are you testing if there is information in a TinyDB?

you can use these blocks to check the particular Tag

Or something else?
