Problem: Windows 10 Anniversary Update path name length limitation with ArcGIS


ArcGIS software is developed and certified to support file system path names with a maximum path length of 260 characters, as defined by MAX_PATH. With the Microsoft release of the Windows 10 Anniversary Update, version 1607, it is possible to extend the 260 character limit for New Technology File System (NTFS) paths.

Solution or Workaround

Continue to obey the 260 character limitation of MAX_PATH. Despite this being an opt-in behavior of the Windows 10 Anniversary Update, exceeding the limit can result in unexpected behavior in ArcGIS and, therefore, is not supported or recommended.
