Batch image converter tool? Keep two folders in sync, one resized?

[NeilF]

OK, I want a simple batch conversion tool that takes my original photo album and resizes it down into a mirror folder.

On subsequent runs it need not convert files that have already been done, only new ones, or ones that have since been updated? If folders have been renamed/deleted in the source folder, the destination should reflect this.

Any suggestions? Looked and had no luck!

Thanks!

Doesn't seem to offer an option to ignore photos already done.

When you're dealing 50,000+ photos, you'd only want to convert the 10 new ones, and not do all of them again

Got down to this scenario, using Photoresize & robocopy.

"D:\PhotoResize400.exe" -f1920x1080 -n -m -u -r "-o Transfering <QT><PATH><SRCNAME><QT><EN>" "-cD:\Pictures_Resized\<PATH><NAME>.JPG" "D:\Pictures"
ROBOCOPY "D:\Pictures" "D:\Xtreamer\Pictures_Resized" *.jpg *.avi /PURGE /S /xo
​

Only problem is, photoresize this will convert/transfer .jpeg files over to.jpg... and then robocopy will see their is a file in the destination (.jpg) not in the source (.jpeg) so remove it.

If only photoresize kept the same extension name! Ive raised this with them

I've got a feeling all my jpgs ar .jpg though!

So your nconvert.exe does the same as my suggested photoresize400.exe, but doesn't lose the .jpg extension name?

Are sub folders done too?
