# Code for WP “file size” Field

 * Hi, David!
 * For my media library ([http://cousin-collector.com/blog/?page_id=690](http://cousin-collector.com/blog/?page_id=690)),
   I’ve been able to use either IPTC metadata or the WP media item information for
   my listings. The one thing that’s evading me is the file size. I see that WP 
   lists that information, but I don’t know the code to access it, so it has to 
   get it from the photo or PDF itself each time the page is loaded.
 * For instance, the first PDF in the list has this line:
 * **Uploaded:** 12 March 2017 **Modified:** 12 March 2017 (293.0 KB)
 * I’m using:
    `{+file_size,kbmb( 1024 , ' KB', ' MB', 1 )+}`
 * But IIRC it would be more efficient to access the WP field for this? Such as 
   with the Description field?
 * `{+description+}`
 * Thanks!
 * Kris

 * Thanks for an interesting question. You wrote “**_I see that WP lists that information…_**”
   I assume you mean that the file size appears, for example, in the “Save” metabox
   at the upper-right part of the Media/Edit Media admin screen; is that right?
 * As far as I know, WordPress does not store the file size anywhere in the database,
   as it does for fields like Description. I did a quick search of the WordPress
   code and found many places where the PHP `filesize()` function is used to find
   the file size. This is the same function MLA uses to populate the `{+file_size
   +}` data source.
 * You could map this value to a custom field, but I don’t think that is any more
   efficient than accessing the value directly when you need it. If `filesize()`
   is good enough for WordPress, it should suffice for your application as well.
 * I am marking this topic resolved, but please update it if you have further questions
   about finding the file size for your application.

 * Hi, David!
 * Just for archival purposes, yes, this is where I’m finding the size information
   in the WP media admin screen:

 * If `filesize()` is good enough for WP, it’s good enough for me.
 * Thanks! 🙂
