Showing File Sizes In MB.

[Tallmanirl]

Hi guys!

Is it possible to get Photoshop CC to show my image size in MB on my Windows 10 laptop? I never see that option. I usually use Windows 10 itself to do this, but think it may be malfunctioning.

In Windows Explorer set the view to details and you will see the sizes of image files on disk.

Alternatively right click on an image file and choose properties to see both the file size in teh general tab and the pixel size in the details tab

Thanks for that Dave. I was using the file properties option to view the MB
size of the files, but this seemed to malfunction last night. I’m wondering
if there is any option to view the MB In photoshop?

Regards,

Fergal.

Inside Photoshop you will see a different figure based on File Size in RAM of the current layers. It is a different number entirely to filesize on disk which is the compressed size on disk along with metadata.

You could use Bridge though and look under File Properties there.

AFAIK the only way to get the saved file's size on the drive is via scripting. As previously mentioned, the size of the image opened in Photoshop may be very different (larger in Photoshop if lossless compression has been used to save, i.e. as a JPEG for example).

Another example of scripting the reported file size is the megapixel size:

Thanks for that. What is scripting?😀

Hi, could you elaborate on where you'd like to see this value? In the open/save menus? In the status bar (hope you are aware this is the size with zero compression)? Which value are you currently seeing?

Hi, again, @Tallmanirl @could you explain the "why" you need to see the size of the files, with all the caveats explained in this thread. Web design? Videogame for mobile? Would you save files flattened, or is the size of layered files needed.

Hi PECourtejoie,

Some photo printers have a 30mb file size limit. I need to know my file
size so I can keep (or reduce it to) less than this.

So, is there any benefit in running a script to show you the on disk size, when this info is available at the file system level?

Would this save time, so that you could run the script, see the saved file size, then perhaps save again using a lower quality level?

What file format do the photo printers require?

Because if they require a JPEG format image (as many photo printers do), commands like Save As and Save for Web have a file size preview built in. This will account for flattening and compression. If the previewed file size is too large, you can then use the compression options to make the number go down before you actually save the file.

If the photo printer requires TIFF or Photoshop PSD/PSB, I don’t think you can know the current size until you save.
