Suppose there is a directory XYZ having too many files (100 to 10000). Each file contain the format like first line having company name and second line some data values. We need to read each files in directory and create the new directories at some path with company names and move that file (1.txt ) to that directory.
what should be design.
My suggestion was to Create a function ScanDir() which will read the count of files and will make loop to read the file and will create a thread for that file and move to next file and process the all files.

Your idea sounds pretty good. I just have a few opinion to add.

1) Well, you have no choice other than looping through them since you have to read all files
2) What if there's a repeated company name

For Repeated company name the directory will be created only once and files will be moved to that directory. But there can be case when two thread having the same company name are executing in parallel then we need to implement synch mechanism (e.g mutex )
pthread_mutex_lock()
if (!checkdirExist())
createDir()
pthread_mutex_unlock()
movefiletodir().
