Re: [ferret_users] what is ferret's limit to the full path name for a netCDF data set

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Janeen,
The length is 256 characters. This allows for long local path names and 
also long DODS URL's. What version of Ferret are you running? What is 
the path you are trying to open?  I created this directory and put a 
dataset into it, for a path name around 256 characters, and opened the 
data successfully.
