@Ruriko You cannot just directly read file size from that binary file but what i have is something what you can do and it works for me:

this isn’t straightforward but should be possible. You can obtain the size of a file by reading the buffer length. Once you have this information available, you could then use an IF node to filer by size, hope this helps.

Hi @Ruriko,

As friends have mentioned, I’d like to add the most straightforward method for future reference and indexing,

Since the binary object now already has a property called bytes, you just need to convert it to the unit you want,

For example, to convert it to MB, you can use this expression:

{{ $binary.data.bytes/1024/1024 }}
