Old and In the Way
Tired of wading through old folders in your file servers? Check out this script.
- By Jeffery Hicks
Most network administrators have a few file servers that are dumping grounds
for old folders and files that no one knows where to keep. These servers often
have files created years ago. Does this sound like you?
Most of you probably have some sort of process to manage this type of situation.
If you're using Windows 2003 R2, it has an excellent file-server management
tool. If you're using another operating system or don't have any utility to
keep track of old files, though, Mr. Roboto is here to pull a tool from his
scripting utility belt to help out.
I've assembled a simple VBScript called FileAgeReporter.vbs. Give the script
a path and it will analyze every file in every folder and subfolder. The script
will prepare a report in comma-delimited text format showing the file name,
its size, the date it was created, the date it was last modified, the date it
was last accessed, its file extension, its file type and its owner. When it's
finished, you can open the file in Microsoft Excel for further sorting and filtering.
Even though the script will gather the last-accessed date, don't rely on this
as an absolute indication of the last time a user actually accessed the file.
Anti-virus scanners and disk defraggers can affect this date. I've included
this date in the script for the sake of thoroughness, but I wouldn't consider
it unfailingly accurate.
Besides the Excel file, the script will also prepare a text-file report with
an analysis of file aging. The report will also list every file type found,
the number of files, the percentage of total files, the total size and the percentage
of total size.

You'll have to run this script from a command prompt using CScript.exe. You'll
also need to run it with administrator credentials: cscript
FileAge Reporter.vbs /folder:path [/norecurse] [/owner] [/verbose] [/?]
The only required property is the path. This can be a local drive, folder,
networked drive or a UNC path. It uses the path to automatically generate report
file names. The script takes the path name, removes the colons and replaces
\ with _. It converts the path to uppercase and appends a timestamp so that
checking folder c:\files\public, for example, will result in file C_FILES_ PUBLIC_20070611214328.csv.
The report files are saved to the same directory as the script, though you can
edit the script.
By default, the script will search recursively through all subfolders from
the specified path. You can override this behavior with the /norecurse
parameter: cscript FileAgeReporter.vbs /folder:D:\Files\Sales /norecurse.
The parameter in that example will give you a set of reports for the Sales folder
Assuming the folder or path is formatted in NTFS, you can also get the owner
of each file. This feature requires Windows Management Instrumentation (WMI),
so the file server must be running some version of Windows. Depending on the
number of files to process, adding owner information will slow down script performance.
To add owner information use the /owner parameter: cscript
FileAge Reporter.vbs /folder:D:\Files /owner.
You can download the FileAgeReporter from my Web site. It should give you some
valuable information on how the file store is growing in your file servers and
how long certain items have been there. This can help you make better storage-management
