Re^2: Random Files Recursively Form Directory

Yes the % is only for the target files(ie 25% should be the extensions specified). Next the data structure would become very big as I have drives with minimum 100GB that means 25Gb(25%) minimum so the time would be quite high (Time for file::find and Filelist prparation + shuffle of filelist). So is there another workaround?

I saw this module File::Random which implements rand functions. I was thinking of using this module in a while loop to iterate over the directory till specified size is encountered. What do you think of this?

I don't see how the size of the files in a directory would affect File::Find, data structure preparation and shuffling the list. I would say that number of files in a directory would have an effect. What is the number of files per directory? I would think File::Random would also be slow if the number of files in a directory is huge. A quick check of the code in File::Random make me think that it re-reads the whole directory every time you call random_file() and therefore you could get the same file returned more than one time.

Each directory consists of atleast 5000 files plus sub directories having atleast 3000 files. But any how it looks like the only possible solution so ill give it a try. Thnks...
