line break for the TODO point

o querying -> by querying ?

I do think here we shall fail the whole (remove the whole path, if there is per path for each log? otherwise to remove all created cmd_files?) in case of having ANY of error?

will `file not find` be counted as an error? As I understand, it shall not?

it's not filename but NoFileInDir ?

better specify `lowercase` or `uppercase`

better use XOR_NAME_LEN instead of 32. btw. would like to confirm that the filename of a chunk is in hex, which will be 2*XOR_NAME_LEN , and it will be ok to be parsed here, right?

hmm... I feel it's bit confusing now, both `id()` and `name()` returns with `XorName` I can understand that `id` is `hash(name+tag)` to be unique probably not expose `name()` (to avoid mis-use) or to make `id()` type safe or give `name()` a more explicit naming, say `service_name` or `content_name` or etc?

is the unwrap then wrap necessary? same to the belows

Can we make this function available everywhere by removing the `cfg` flag? This might be useful during the data replication flow.

Fixing this `Chunk` in comment.

Adding comments here to clarify when this is to be used.
