i have been trying to use blackbox ftp 1.2 for awhile and it seems that connecting and browsing the ps3 file structure works great and i have 0 problems with that. where i have problems is when i try to move a large backup i get tons of timeouts, ps3 will return to XMB randomly, and other odd errors. it seems that it is having a hard time creating directories while moving just files seems to work OK most of the times. any advice?

*edit*
smartftp seems to work perfectly. how many workers (connections) can i have running at the same time?
