Windows 10: PowerShell not-even-noob needs help with script to locate pairs of fil

I have organized my photos by YYYY-MM-DD for use with Adobe Lightroom. (which works Ok for me, maybe not for everyone else ... )

Until about 2 years ago I shot NEF+JPG, meaning I have both the RAW file and the JPG for every photo. But since I've gotten more proficient in Lightroom (which ain't exactly easy ...) I now realize *Confused that I don't need the out-of-camera JPGs. I have probably thousands of these JPG files scattered over many directories and subdirectories, which only clutter my folders and waste at least 200 GB.

Can someone help me out a PS script that would list out folder by folder, which NEF files also have a corresponding JPG? I'm kind of an old-timer. Before using DOS, I was using CP/M on a Z80 machine with ... 64 KB of RAM and 2 1.2 MB 8" double-sided, double-density floppy drives. Then I got an early PC AT clone with 640 KB of RAM, plus extra with some card called "Six Pack." So I know the DOS bat/cmd script, but I have never been able to master PS.*Sad

Whenever I create a derivative JPG file from an edited JPG, I now export to a different set of folders. *Smile

Once I get this PS working, I think I'm smart enough to figure out how to adapt the script to look for any JPGs that were created at a later date, meaning those are derivative JPGs that I stored in the wrong folder (before I got skilled enough with Lightroom's complicated workflow. *Wink

Thanks in advance. Many thanks.

powershell newbie needs help

I am very new to powershell (long time DOS user)

I have encountered several issues

1. When I run a perl script from powershell a new pops open the perl script runs and then the window closes. Do I have any control over this behaviour ?
2. when I run an external program how do I pass the value of an environment variable to the external program without cutting and pasting the value from a "dir env:" listing ?

Thanks.

 

PowerShell scripts not working with Call operator

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are facing issues while developing a PowerShell script using the Call operator. I would suggest you to refer the articles

The Windows PowerShell ISE.



However, as the issue is related to developing PowerShell scripts, I would suggest you to post your query on

MSDN forums, where we have expertise and developers who are well equipped with the knowledge of developing PowerShell scripts in Windows.
