Ok, after some search and reading on other related threads, I decided to go for free CloudOn app. Funny thing is that I was stuck at the beginning: open MS word and instead of showing a Word window with menu on top, it pop out a small window asking to create a new file/type file name with no option for opening a file. The only other option is "cancel" that will close Word. I remember when opening Word, it's window shall open with menu "File" for choosing "New File" or "Open ..." etc. Now to start using CloudOn's Word, it won't give option to open a file? How is this? I sort of reading that CloudOn let users open files on ipad and connected mac which are not stored in DropBox. If open Word (or execel..) gives no option to do so, then how to tell CloudOn to find/open those files not in dropbox? Does it require all files be stored in dropbox ? Can I just use CloudOn for only reading my files which have no need to be stored in dropbox? Thanks for answering my questions.
