The FSRM stores it data in a file called quota.xml which is located at C:\System Volume Information\SRM. To get at it you need to be running as System account. So lets start.

Fire up a CMD windows as System

TheDriveYouWant:
net stop quota
net stop datascrn
net stop srmsvc
cd "\System Volume Information\SRM"
attrib -s -h quota.md
attrib -s -h quota.xml
copy quota.xml %temp%\quota_%computername%.xml
copy quota.md %temp%\quota_%computername%.md
attrib +s +h quota.md
attrib +s +h quota.xml
net start quota
net start datascrn
net start srmsvc

So now we have the XML and md files with the settings in them. In case you want to play around or move them to another server.
