Problem writing on a TileDB array with long file path Windows

[giordizz]

I get a TileDB::IO exception (File opening error - Failed to convert URI) when I try to write (not create) a TileDB array located in a filesystem directory Windows with a long path.
Is there any known limit about a directory path length?

Hi @giordizz, currently the limit is the win22 API MAX_PATH of 260 characters. Because of various aspects , effectively this means the array path needs to be under 166 characters. I've opened an issue to fix support for NT-style extended paths (\\?\C:\...) which do not have the path-length limitation -- currently not supported -- and we'll look in to moving to the newer APIs without the MAX_PATH limit as soon as possible.
