Determining the Size of a File

This tip applies to Word 2007, 2010, 2013, 2016, 2019, and 2021

One of the nice things about writing macros is that you have the ability to do just about anything you can do using the regular Basic language. For instance, you may want to open and process some text file within a macro. Before doing so, you might want to know how large that file is.

You can figure this out using the FileLen function in VBA. It returns the length of a specific file, in bytes. You don't even have to open the file first; just provide a file name, and FileLen does the rest. The following is an example:

lFLen = FileLen("TargetFile.txt")

This code determines the length of the TargetFile.txt file and assigns that value to lFLen. The value returned is a long integer.

Note:
