Open Files for a process
I am having a client/server application which will download files from server. If server has directories, it will create directories/sub directories and then download files. In this process, I observed that number of open files are more than 400 (which is approxmately same as number of dir/subdir that I downloaded from server) using "lsof -p pid" command. The o/p of lsof command has "DIR" Type files with file descriptor as "Read".
I did't understand why the Type "DIR" is in read mode. Under what conditions it will take place?
