copied!<p>Just open the file yourself for block reading (not using TStringList builtin functionality), and read the first block of the file, and then you can for example load that block to a stringlist with strings.SetText() (if you are using block functions) or simply strings.LoadFromStream() if you are loading your blocks using streams.</p> <p>I would personally just go with FileRead/FileWrite block functions, and load the block into a buffer. You could also use similair winapi functions, but that's just more code for no reason.</p> <p>OS reads files in blocks, which are at least 512bytes big on almost any platform/filesystem, so you can read 512 bytes first (and hope that you got all 10 lines, which will be true if your lines are generally short enough). This will be (practically) as fast as reading 100 or 200 bytes. </p> <p>Then if you notice that your strings objects has only less than 10 lines, just read next 512 byte block and try to parse again. (Or just go with 1024, 2048 and so on blocks, on many systems it will probably be as fast as 512 blocks, as filesystem cluster sizes are generally larger than 512 bytes).</p> <p>PS. Also, using threads or asynchronous functionality in winapi file functions (CreateFile and such), you could load that data from files asynchronously, while the rest of your application works. Specifically, the interface will not freeze during reading of large directories. </p> <p>This will make the loading of your information appear faster, (since the file list will load directly, and then some milliseconds later the rest of the information will come up), while not actually increasing the real reading speed.</p> <p>Do this only if you have tried the other methods and you feel like you need the extra boost.</p>
