Hi Everyone,

I do lot of photography and since each picturave 2 file (raw and Jpeg) ill review them first in Jpeg since its faster than check the raw and then i delete the picture i dont want but it left the raw in the folder.

im trying to make a scriptes who check the folder files and erase all file who are alone, like if the script see the picture 001.jpg and 001.raw then its fine, but if the scripte see 002.jpg only (or raw) then he erase it.

Hope its clear and someone will have a soluce.

Cordialement,

Dino

You can take this code and possibly pipe it or use a foreach loop to delete the results where the file count is 1. Obviously, you would change the code from -gt to -eq.
I will say though, this code hinges on the filenames matching exactly for your jpg and raw version.

Get matching file names with different extensions Programming & Development

I’m learning how to do something with powershell, but something tells me that you guys will answer this for me faster than I can finish watching all of the Powershell videos on Microsoft Virtual Academy, which I will do either way :). I’d like to get all the files in a directory and all subfolders that have the same name, but different extensions. For example: [2015-12-21_10_40_33-Testing_FileName.png]TestDoc1 exists twice, once as a docx and once as a txt. The same is happening within the su…

as long as the name match (e.g. 123.jpg and 123.raw) that should be do-able.

What have you tried? where are you stuck?

I’d probably

iterate through ALL of them (get-childitem -recurse)
group them by *.jpg (group-object)
run a foreach ( *.jpg ) to see if each *.jpg has a *.raw match
list the ones that don’t have a match.

If we are taking about thousands of pictures, that can be a rather long / slow process.

Give it a try. We’re not a script writing service, but happy to help if you put some effort into it.

Neally’s got the algorithm.
After you clean up once, future runs should be fast.
