Probably file path is too long. You need special programming techniques to access filenames longer than 250 characters on Windows.

Latest Slicer Preview Release is a bit more robust to very long filenames, so if you use that then it may be enough to move the files from `H:/Berbeco Lab/Studies/AGuIX/Ratio_AGuIX-Bi/MRI Data/MRI Linac/MRI_Data_Slicer` to `C:\tmp` and import from there.

If these don’t help then follow instructions in the link that @pieper provided above.

Shortening the file path/file name allowed me to import the data. Thank you!
