Celerra CIFS Share scan for specific filetype

The CIFS fileshares on our Celerra is running out of space and I would like to know is there any freewares/tools to scan a CIFS Fileshares for Audio/Video files and generate a report in excel/csv format for each user.  I know there are tools like VSRM. Rainfinity FMA etc to scan for a specific file etensions on a CIFS Share but I donot have that in our environement.    Right now I'm forced to do unix "find" command under the root_vdm/fsname to get some information but formatting it taking time.

Thanks in advance.
