try using find command with -type f -mtime +30 -exec rm {} \;

This will go within subdirectories. Or before actually deleting you can just list them using find command with -exec ll

Also, you can use "ls -lR" which is recursive long listing for examining the content. Also "du" command will list all the files including subdirectories and files with their size.

Also, use find command with -mtime option, (best way to find and delete) as posted by previous poster.

Thanks

List all the files
#find -type f -mtime +30 -exec ll {} \;
#find -type d -mtime +30 -exec ll {} \;

Make sure those files are not required then you can remove them using

#find -type f -mtime +30 -exec rm {} \;

A minor note:

It's more efficient to pipe find's output to xargs. (find ... | xargs rm -f).

If you have many files, xargs will only be invoked a few times, whereas rm (from -exec rm) will be invoked many times.

Just a minor note.
