I've tried On_Air_WiFi_Disk and WiFi-File-Explorer-PRO and neither get the job done.With On_Air (made for macs) the SD card mounts in the computer's Finder, but when I open it there's a flash of the directory contents which disappears and the SD unmounts.WiFi_File_Explorer interacts with an FTP client on your desktop computer (I tried FireFTP on my Firefox browser) which reads up a directory (which at least doesn't disappear) that cannot be interacted with - just hangs/freezes when you try to move anything to or from the SD. I picked up SwiFTP, and had even worse luck, couldn't even see the PDN. All three seem to be passive FTP servers. Is it a permissions thing, security issue, or I'm using the wrong programs and there's something more compatible? Please don't tell me it just can't be done and I'm lucky to have gotten as far as I did. I'd rather hear the problem is between the chair and the keyboard.Also looked at AndFTP, a client not just a server, which looks more involved than I would hope to have to deal with since I'd have to set up a server elsewhere on my network. The click and forget of the first 3 apps I tried seem ideal, but aren't working for me ... yet.Your input is appreciated.
