App-specific Help
If you are having problems with a specific application, check here first to see if there are solutions.
VLC Media Player
Since ExpanDrive looks like a local hard drive to most applications, certain behavior you would expect from files on a network is not exhibited. This is especially true of streaming media apps like VLC, which generally store some data in a cache to smooth out performance. When VLC thinks the media file is local to the computer, the amount of data it prefetches is very small. You can change this and in turn improve performance for any media files you have on ExpanDrive.
First, open VLC and go to preferences.
Make sure the little box labeled 'Advanced' is checked, and then select 'Input/Codecs'→'Access Modules'.
Click on 'File'.
There, set the field 'Caching value in ms' to somewhere between 4000 and 30000, depending on the speed of your internet connection, and the type of media you generally play.
If you play mostly video, you should experience better behavior if you use a somewhat larger value (greater than 10000).
Eudora
If you want to back up your Eudora folders to ExpanDrive, you must first know that Eudora stores some important information in a data structure that is incompatible with filesystems other than Mac OS X's HFS+. This information is discarded when the file is transferred to another filesystem. Archiving the file preserves the data, so before transferring Eudora folders to ExpanDrive, archive them as a .sitx or .zip file.
