Hi,
I use imagemin-cli 3.0.0 with imagemin image/* --out-dir image but i got the following error:
Error: Error in file: image/Thumbs.db
EPERM: operation not permitted, open 'myFolder\image\Thumbs.db'
I see that it comes from the thumbnails generated by Windows 7 but I think this file should be automaticaly black-listed from the list of the files to process.
