I can look at in a few hours
Should be minimal updates

Finally had a moment to get back to this.

The script now works in Windows 11. The main issue was that since Windows 11 the concatenation of path with the file names process changed I had to change the code to accommodate the needed change

Thanks for that

No problem

how would I be able to get this to work for MP4s as well in the same folder? I tried adding that in the ImgsFound to include '*.mp4' but did not work

Typically video files in general do not have the needed EXIF information.

Appreciate the quick response. Do you have any suggestions on how I could do this with photos and videos inside? Seems powershell can't handle it if I want the date created

ah it looks like videos use "media created" and not "date taken"

Even that "media created" can be misleading depending on the device used.

If you look at the date created value you can get from get-content that may help.

I had a script that would pull that and rename the videos but similar to this powershell script when Windows 11 came out the process changed just enough that it doesn't work.

Get-ChildItem -Path video.mp4 | select Name,CreationTime

If you do a loop within the directory of your video files this could work.

By all means try out each field and see what works best for you

The $ImgData.Dispose() happens outside of the error handler, which performs continue if there is an error. This puts a lock on the files. Should perhaps be refactored to dispose before continue on next file.

Thanks for this sample, I'm working on an updated script that includes the ability to read LastWriteTime if there are no EXIF data available.

Good catch, I mostly use a bash/shell version of this script now but would love to see your update.

Hi! Just wanted to say thanks for keeping my script alive and mentioning me as the original author 😀

Thank you for doing the initial work, it has been a great script.
