How to increase the size of a shared folder

I created a new shared folder,and I want to copy 790GB data to this folder.Windows 7 popped up a dialog box “There is not enough space on bak(\SWandHYsStorage).You need an additional 784 GB to copy these files. Space free:6.61 GB
Total size:445 GB”.

However, if I copy the 790GB data to the Public folder, it is fine and it only takes 1% space. How shall I increase the size of the shared folder?

Your PC has connected to that share on the MBL via WebDAV instead of normal Windows Client connection.

Windows thinks the MBL is full because your primary disk drive in your PC is almost full.

Search the forum for WEBDAV for more info.

Thank you.
