Hello,

I'm working on a batch file that backs up data and I want the file to show the current file size in bytes, kilobytes, megabytes, and gigabytes. I know how to get the file size in bytes, but converting it is the problem. I know I can do [size in bytes]/1024 to find the size in kilobytes, but this doesn't always work due to 32-bit floating point limitations (i.e. doing "set /a var=1564231685254/1024" yields this error: Invalid number. Numbers are limited to 32-bits of precision).

Is there any way to get around this?

Thanks in advance!

You can use Windows Scripting Host and VBS or Jscript.

Also google for Timo Salmi's msdos and batch faq and you might find some sample code.
