Sharing Preferences
These settings may benefit workflows in which multiple clients are performing read/write
operations on the same files.
Property
Deferred
Select this option when you wish to prioritize the file close operation and delay the
sharing and transfer of modified data to the Harmonic MediaGrid. This may be useful when you are
writing to a large number of files, and other clients do not need immediate access to
flush mode
the files after you have closed them.
Deny delete/
Select this option to prevent other clients from renaming and deleting a file that is in use
rename of files by this client.
Note: This setting does not override the Windows FILE_SHARE_DELETE flag. If Deny
delete/rename of open files is checked and the FILE_SHARE_DELETE flag is set, then
other clients that attempt to rename or delete the same file will be allowed to do so. If
Deny delete/rename of open files is checked and the FILE_SHARE_DELETE flag is NOT
set, then other clients will not be allowed to rename or delete a file that is in use by your
client.
User Credentials
Windows FSD stores a list of up to five user credentials for connecting to the Harmonic
MediaGrid. If one set of credentials fails when connecting, another connection attempt is made
using the next set of credentials on the list. If the Windows FSD is not able to connect after trying
all saved credentials, then you will be prompted to log in.

This setting allows you to limit the memory usage for caching
file data in the Windows FSD. The default value for this
parameter, 400 MB, is sufficient in most cases. If your
workload requires many files to be read simultaneously, you
may wish to increase this number. If you are unsure of whether
you should increase or decrease it, please contact Harmonic
Technical Support for assistance.
The maximum allowable value for this setting is 25% of your
system's RAM. This is calculated after RAM for other drivers
(for example, graphics) has been allocated. Therefore, the
maximum value enforced for this parameter may be smaller
than 25% of the total system RAM.
This option can improve performance for specific workflows by
altering the behavior of file reading in the FSD, and is
particularly useful to non-linear editing applications.
By default, this option is turned off. Leave this option
unselected for all other applications (for example, archive or
office applications).
