Here is a scheme that will both eliminate qdirs and allow long file names.
At the present time (Comet 2005 development), there are only 2 reasons for a qdir:
1. It holds the comet dir name
2. Info about sequential and contiguous files is kept there
All other file info can be found in the file itself.
If an open searched the windows folder for the file, and applies logic based on the file's extent ion, we would not need to read the qdir and the file could have a long file name (up to 255 bytes even).
The difference may be this:
1. Files would be found that would not necessarily have been found in the qdir such as exes.
2. The system would not be compatible with older versions of Comet.
3. Performance may suffer depending on the number of files and the speed of the windows calls to "find first" and "find next" vs. the speed of a comet keyed file read.
4. If we make a change, it would be made in some version of the file system (CFAM only), and would be an all-or-nothing change for every installation.
I am very willing to make such a change. What do you all think?
