In FancyCache 0.80:
1. Enable the option "No Write-Flush at Shutdown"
2. Exit FancyCache admin screen so that it will save its options.
3. Open FancyCache admin screen again and click the button "Flush Write".

Please note that even you enable "No Write-Flush at Shutdown", program still will write certain amount of data to the disk when the free cache space is insufficient (so called Urgent Wrte). In such scenario, it may cause that some files are only partially updated by Urgent Write, but not fully updated because of no flush at shutdown.

Thanks for furthur explanation!
Suppose you enabled the option "No Write-Flush at Shutdown" and there is free cache space and you click the button "Flush Write" , will all the changes be fully updated after restart?

"Flush Write" command will flush all currently deferred write-data to the disk, even you enable "No Write-Flush at Shutdown". It is a manual flush command.

Thank you!
Please try to bring back the option "No Write-Flush at Shutdown" to PrimoCache...it's very useful!
Thanks in advance!
