1.     Does FileLock support removable media?

Yes, provided the media is formatted with an NTFS file system.

2.    Does FileLock support SANs, "Storage Area Networks”?

In a SAN’s environment, FileLock runs on the Windows machine on which the FileLock protected NTFS SAN volume is mounted.

3.    What storage hardware does FileLock support?

FileLock is hardware independent.

4.    Can I FileLock protect my primary Windows volume; i.e., drive C:?

Storage Clarity does not recommend FileLock enabling drive C:, i.e., your boot drive.  There is a possibility that FileLock could be configured in such a way that it may interfere with both the booting of the host and the running of the Windows OS. 

5.    How can FileLock be so simple and work in terms of file retention and destruction?

Grau Data designed FileLock to be simple and effective.

6.    Can FileLock prevent premature deletion of files by the manipulation of the host time?

Yes, FileLock provides a secure and compliant retention time management system, called “Verified Retention Clock” (VRC).  VRC monitors the host clock time and FileLock protected volume activities.

7.     Ok, I’ve changed my mind and I want to delete one or more files prior to the retention time expiring?

Not possible; that would defeat the purpose of FileLock.  You cannot shorten the set retention time.  You can extend the set retention time.

8.     Does FileLock support virtual environments?


9.     How do I backup a FileLock protected volume?

Not all backup software will properly backup a FileLock protected volume.  Most sector/block level backup programs will work.  File level backup programs, unless they are FileLock aware, will not work.  For additional information, please refer to the FileLock administrator manual and/or contact Storage Clarity.

10.   Does FileLock work with Virus scanning software?

Yes, FileLock has been tested with a number of virus scanning software packages. Of course, if your virus scanning software finds a file in a FileLock protected volume, it will not be able to delete the file.

11.   How can I remove a Virus from a FileLock enabled volume?

While the Virus infected file(s) are protected by FileLock, you will not be able to delete or modify the file(s).

12.   I have moved my FileLock protected volume to another host and FileLock is now reporting that my previously licensed volume now has an evaluation license.  How do I restore my permanent license?

There are several known issues with FileLock licensing and moving FileLock protected volumes between hosts.  If a FileLock protected volume reverts to an evaluation license, please contact technical support.

13.   Unable to read/write files on a FileLock enabled volume.

There are couple of typical reasons for this.  First, the FileLock license maybe invalid.  This can happen when an evaluation license expires.  Second, you have mounted a FileLock volume on a host that does not have FileLock installed.  You will need to install FileLock.

14.   My electronic document management system uses NetApp’s SnapLock protocol to manage file retention and destruction.  Does FileLock support SnapLock?

Yes, FileLock supports NetApp's SnapLock (i..e. magnetic/erasable WORM volume).  Select single file retention when configuring FileLock for the volume. 

Please note:  Netapp has recently released a new ONTAP OS on many of its new storage appliances that does not support SnapLock.  You can add Snaplock functionality to these Netapp appliances with FileLock.



1.     How difficult is it to install and configure FileLock?

FileLock was designed to be very simple.  FileLock only takes a couple of minutes to install and configure.



1.     How do I try out FileLock without buying a license?

You do not require a license to install the FileLock software on a host computer.  Just download and install FileLock.  Without a permanent license key, FileLock creates FileLock enabled volumes with a 60-day evaluation/demo license.  To request a current copy of FileLock, please click the following link: http://storageclarity.com/FileLock-Demo-Request.html .

Please note: (1) FileLock evaluation/demo volumes have no capacity limits; (2) Can be converted to a fully licensed volume provided the evaluation/demo license has not expired; (3) Once the evaluation/demo period has expired, file and directory data on the FileLock enabled volume can never be accessed, nor can the volume be converted to a fully licensed volume.

2.     How do I obtain a license for a FileLock?

FileLock licenses in North America are available through Storage Clarity.

3.     With removable media, where does the FileLock license reside, host or media?

With direct attached non-removable storage and network attached storage, the FileLock license resides with the Windows host running FileLock.  With FileLock supported removable storage, the FileLock license resides on the removable storage device.  This means you access the FileLock protected removable storage device on any Windows host running FileLock without any additional licensing.

 4.    How is FileLock licensed?

FileLock is normally licensed by capacity, on either a host or volume basis.  Please contact Storage Clarity for details on FileLock licensing.



1.     Can I replicate FileLock protected volumes?

Yes, FileLock includes a replication service that allows you to replicate a FileLock protected volume to another volume on the same or a different host.



1.    Is FileLock DICOM, SEC 17a-4a, SOX, HIPAA, etc. Compliant?

There are a number of United States government and industry rules/regulations dealing with the retention, destruction and security of unstructured file data.  When properly configured, FileLock will preserve records in a non-rewritable, non-erasable WORM (Write Once Read Many) format, for a user specified time period.  It is Storage Clarity’s opinion that when FileLock is configured with Enhanced Security Mode turned on, FileLock meets the requirements of many storage compliance rules and regulations.  For additional info on FileLock and compliancy, please contact Storage Clarity.
