Copied folders and files into the Dropbox file system on a windows machine. On my LG android, the Dropbox program shows the file structure as it should be with all the folders and files in place. However, the FX and Explorer file managers on the android do not show some folders and a lot of the files, for example, down in a third level folder, only 2 of 16 files are listed. On an older Milestone android, very few folders and files are listed. The dropbox system works well on PCs and an Ipad, so there appears to be a serious problem for dropbox on androids.
