# I appreciate the way you guys help people here.

# Thanks a lot.
Q 1: How can i get the extension of a file ($file)?
e.g. $file could be anything me.jpg, one.exe, two.psd etc.
i only need the extension.
Q2: Sizes and number of files and sub-directories.
Let me explain what i actually need.
Suppose I have a main directory (maindir).
maindir has sub-directories (sub-dirA, sub-dirB, .....)
Every sub-directory could have further subdirecties (sub-subdirA1, sub-subdirA2, sub-subdirB1, ........)
These sub-subdirectories have files in them.
Note: please note that subdirectories cant have files in them. only sub-subdirectories have files.
I need to find: the total number of sub-directories. total number of sub-subdirectories. total number of files in all the sub-subdirectories and total sizes (combined sizes) of all the files.
Q3: I need to build a list of recently uploaded files.
I have all the info like, file name ($filename), user who uploaded the file ($username), time and date ($timendate), sub-subdirectory where the file is uploaded ($subdirectory, $sub-subdir). I need to save this info of $x number of recently uploaded files in record.txt
$x could be any number defined by the programmer in the code.

Q4: And then i need to seperately retrieve info of the uploaded files.
The last 10 uploaded files were abc.txt, tnt.pl,.....

Thanks again.
