Rajesh - there is an upload size limit in the web.config (~8MB), but the only limitation to the storage within a folder would be your file system's limits. There is also a host setting in your portals that can control the disk space the portal folder can occupy, but I would doubt if this is in play. Hope this helps.

My issue with the folder size limit and not the file itself. When I go to the file upload a file on any portal it says unlimited in the file upload screen but once you reach 100mb the system say "file folder size exceeds the limit:100.00mb.  How can this be changed? I would like to increase some portal over 100mb and some I would like to keep at 100mb. Can this be done?
