Organize image files by resolution

[Convidado]

Hello - Would like to script something to separate hi res and low res images that reside in the same folder, by either moving one or the other to another folder or deleting the lo res altogether. This should be a one time operation of a several hundred files (possibly over a thousand), so apple or java would work.

I have several applescripts to identify the properties of a file, but it is a slow process doing one at a time and then having to find/delete the fie. UGHH.

If I need to do this on Windows, I open up Explorer with a Details view then sort by Dimensions and just highlight and delete the ones that are obviously thumbnail size.

Unfortunately, I have to do this by file resolution because the low res are the same physical size as the hi res and both are jpg, so the file size for a low re and hi res can both be under 100k.

I need to remove all files in the folder that are under 300 dpi.

I see, by "resolution" you mean print-resolution, not pixel-dimensions. Windows Explorer can also display and order a details listing by Vertical Resolution or Horizontal Resolution.

What version of Photoshop are you using? There are several ways to automate sorting the files. If you already have Exiftools installed I would start there. If you are willing to learn it's command line syntax I would still recommend that approach.

If not I would use either a Bridge or Photoshop script depending on which version of Photoshop you are using.
