open in external application

Hi

I’ve been using Arbil for some time to classify video clips and photographs of sign language. Those photos and video clips, I import directly from my pc.
Only when I want to use “open in external application” the message that appears is “failed to find the file : failed to open file:/C:/Video… Error message : paramètre incorrecte”. I tried both the files I placed in “working directories” and the files I imported into “local corpus”, the problem remains the same.
Although the documents are all files with the ending mpg or tiff…

Thank you in advance,
Justin Debroux

it’s ok
