The database itself should create that directory. No need to use os.Mkdir.

Thks, I will test it

Same mistake panic: frostdb.New failed initializing meta DB: sync frostdb\databases\test\wal: Access is denied.

I would check the permissions of the directory that the program is running in. It seems like the program doesn't have permissions to create a directory in the frostdb dir. This doesn't appear to be a FrostDB issue but a local permissions issue.

Alternatively you could update your test to perform a MkdirAll("frostdb\databases\test\wal", 0755)
