Hello,I need to load about 400 files with the C API to work on each pixel temporal dimension. I would like to make a look to load them but fail so far...

Yann, Is that the first error reported? Does it occur for i==0 or much later (perhaps around the 250th file)? Many operating systems have a limit on the number of files that can be open at once, in some cases around 256.
