How can I increase public folder size?

I can copy files to the Public Folder through web access but it only allows me to copy 53GB.

I turned off WEB client  and changed network provider order but no luck

How can i increase Public folder size?

I believe (caveats for being totally wrong) there is no folder size limit, and nothing adjustable at that.  If you have a limitation it’s got to be a network or front-end limitation.

its also showing a file system of fat, whereas it shows up as ntfs on mine. 

although that is when i have a local drive map its ntfs, but when i map over wd2go it does show fat.

although mine shows 297gb on a 2tb drive, odd 

you might want to try backing up your data off the drive, and doing a factory restore on it.
