Even though DiskChecker.mkdirsWithExistsCheck() will create the directory tree, it is only called *after* the enumeration of directories with available space has completed. Directories which don't exist are reported as having 0 space, therefore the mkdirs code is never reached. Adding a simple mkdirs() -without bothering to check the outcome- ensures that if a dir has been deleted then it will be reconstructed if possible. If it can't it will still have 0 bytes of space reported and so be excluded from the allocation. Contributed by Steve Loughran
