Not able to see feeder files

Hello Experts ,
i'm struggling to get answer/solution for one problem.
i have few cubes where i have some calculations. for calculations, i have written rules and feeders.
i can see that consolidations are happening properly without any issue. with enabling zero suppression also i'm able to see the consolidations correct. i restarted the services and server and everything seems perfect.
but here is a challenge
, after updating the rules and feeders, i went to data folder to delete the existing feeders file and i noticed that, ".feeders" files doesn't exist for any of the cubes.
To check,I have copied the data folder from remote server to local PC and there after restarting i can see the .feeder files for all the cubes.
Note: i'm using TM1 10.1.1 in windows 2008 R2 Server.
Could you please help me, am i missing anything here???
Thanks

I assume that you don't have persistent feeders turned on in your config file?

Hi Declanr,
Thanks for the response. yes Persistent Feeders is off in the config file.

Then obviously
you wouldn't expect to see .feeders files then would you?

Sorry for the late response. Actually am not aware of persistent feeders concept. Thanks everyone for the quick help.

Before asking a question at least
perusing the basics in the
documentation is worthwhile.
Using Persistent Feeders
To improve reload time of cubes with feeders, set the PersistentFeeders configuration parameter to true (T) to store the calculated feeders to a .feeders file. Any installation with server load times of over 5 minutes can probably improve their performance using this parameter.
For more details about the associated parameter for this feature, see PersistentFeeders.
When this parameter is set to T and the server encounters a persistent feeder file, it loads the saved feeders which reduces the time normally taken to recalculate those feeders. Feeders are saved when the data is saved or rules are edited. You do not explicitly save the feeders
For installations with many complex feeder calculations persisting feeders and then re-loading them at server startup will improve performance. For simple feeders, the time taken to read feeders from disk may exceed the time to re-calculate the feeders but most installations will benefit.
Using the Persistent Feeders feature will increase your system size on disk only. Memory size is not affected by the use of this parameter.
If Persistent Feeders is off then the feeders are calculated directly on server load. You can only (fully) clear them by commenting them out in the rules file, re-saving the rules, and rebooting the server.
