ID:18537 Intel Quartus Prime attempted to access a project in a directory path that could cause database files to exceed the maximum file length for the operating system. To resolve this issue, move the project to a directory closer to a root drive. The following path to the project's /qdb directory has <length> characters, but only <maxlength> characters are allowed: "<filename>".

CAUSE: Some operating systems do not support path names over a certain size. Since Quartus Prime uses the directory system to implement its database, Intel does not allow projects to be located in very deep paths as this is likely to cause errors in the underlying operating system when the database is accessed.

ACTION: Move the project to a directory closer to a root drive.
