Mpq file system optimization (continued)

God, parsing by yourself (listfile) is an error!

Because stormlib has already parsed itself when opening the mpq file, there is no need to do so!

Besides, although caching the file tree by yourself will speed up searching and enumeration, it takes too long to construct the tree from a string ~~~

This leads to a very serious problem: Slow startup .......

For the file tree, the game is useless, because when the game reads files, no matter what directory, you can view the directory as part of the file name.

In other words, there is no directory in the mpq package!

When the editor needs to list files/folders, You can enumerate all files and then judge the string:

// Configure <br/> array <string> <br/> mpqarchive: listfiles (const string & dirpathinmpqarchive, const string & pattern) <br/>{< br/> array <string> result; <br/> string filemask (dirpathinmpqarchive); <br/> filemask. substitutechar ('/', '//'); <br/> If (filemask [filemask. length ()-1]! = '//') <Br/>{< br/> filemask. append ("//"); <br/>}< br/> filemask. append (pattern); <br/> // start to find <br/> sfile_find_data finddata; <br/> bool found = true; <br/> handle filehandle = sfilefindfirstfile (this-> mpqfilehandle, filemask. ascharptr (), & finddata, null); <br/> while (0! = Filehandle & True = found) <br/>{< br/> result. append (string (finddata. cfilename ). extractfilename (); <br/> found = sfilefindnextfile (filehandle, & finddata); <br/>}</P> <p> return result; <br/>}< br/>

The following is my "unit" Test Program (hey, pack a nice name). It will not take more than 2 seconds to run. In debug mode
