Batch Script to Resize *.jpg in Folder and Subfolders

Post by Erik_IG »

Hi all,

I am looking for an automated process to periodically let NConvert resize all my .jpg files on a server based on folders and subfolders.
Currently I got a script working but that one only allows resizing the files in the specific folder, I need it to include all subfolders as well.

Code: Select all

nconvert -overwrite -ratio -rtype lanczos -rflag decr -resize 1920 1200 *.*
Any idea what I need to include into this script to get it working on subfolders as well ?

Many thanks,

Erik

While the GUI XnView software (XnView Classic, XnViewMP and XnConvert) batch convert functions all have an option to keep the folder structure, there is no mention of a recursive option in the NConvert Help file, and the following posts seem to suggest that recursion isn't supported:

recursive

I'm no command line expert, but when the folder structure is fixed, could the desired result possibly be achieved by using wildcards in the file paths??

If you do try that please proceed with great caution, and it would be interesting to know the result... :wink: :?:

Hello,
Maybe you can try something like that, with a find cmd (here for linux) ( in a terminal, find "." from the root directory of the jpg)

Code: Select all

cd yourrootdirectoryofyourjpg
find . -iname "*.jpg" -exec nconvert -overwrite -ratio -rtype lanczos -rflag decr -resize 1920 1200 {} \;
