“Moving files on and off your iPad with iTunes is fun and all, but what if you also want to exchange files with your iPhone or move files around on the device with your Windows PC? DiskAid 4.0 from DigiDNA may be a cross-platform i-file manager option for you.
Announced on Thursday, DiskAid 4.0 is basically the File Sharing panel of iTunes’s Apps tab, baked into a separate application with a few surprises sprinkled in for good measure. This new version can shake hands with file-management apps such as AirSharing Pro, FileMagnet, and DigiDNA’s own FileApp on iPhones running OS 3.1.3 and the iPad running iPhone OS 3.2.”
