Re: Flock to Rename Directory

[MidLifeXis]

Also look at the penalty of large directories. Some filesystems degrade after a certain number of files.

I would agree with others that avoiding a database of one form or another is not necessarily the best course of action. The file system, after all, is just being used in this case as a database.

If you do not want to use a full RDBMS, then perhaps something like DBM::Deep or DBD::SQLite might suit your needs.
