I have a millions of files under a directory. I don't want get all the files from that directory using the following code snippet File file = new File("C:
files"); String[] files = file.list() or File[] files = file.listFiles(); which would kill my server. Is there a way such that i can get first 25000 files from directory and process them and get the next 25000 and process them and so on... I tried but didn't find help on this one Any help is greatly appreciated

One way I found was to look beyond java for it, using the OS shell commands -- detecting if its windows or unix and running dir or ls with its various options Run the command as a thread and get access to the process's stdout / stderr and process the stream. It is usually quicker than JAVA API's access to the filesystem. It's a bit more complicated than the simple java api, but the performance improvement is worth it.

Please,

 

Could you write a code example for this problwem?
