I don’t believe in reinventing the wheel, especially when it is as good a wheel as FolderSync. If you use dropbox, or any other cloud storage, you really need FolderSync anyway. With FolderSync Lite, it is trivial to setup a two-way sync between your ChordSheet files and a remote folder in your dropbox acount. This will keep all your ChordPro files up-to-date on your Android or iOS device and synchronize all edits/additions/deletions both ways. The FolderSync Full ($2.29) version supports SkyDrive, Dropbox, SugarSync, Ubuntu One, Box.net, LiveDrive, HiDrive, NetDocuments, Amazon S3, FTP, FTPS, SFTP, WebDAV or windows share (Samba/CIFS) accounts, and support for more platforms are planned. There is no way we could/should/would add all these features into ChordSheet, and with FolderSync doing it perfectly, there is no need for us to duplicate their amazing features.

Here are the steps to synchronize ChordSheet with your files in dropbox with FolderSync:

1. Create an account for your dropbox (or SkyDrive,  SugarSync, Ubuntu One, Box.net, LiveDrive, HiDrive, NetDocuments, Amazon S3, FTP, FTPS, SFTP, WebDAV, etc…)
2. Create a folder pair for your local Android folder (e.g., /Android/data/com.qynx.chordsheet/files) and your remote dropbox folder

For safety, start with an empty local folder and specify one-way synchronization from remote-to-local. After the first sync has finished, and your local directory is fully populated, you can change to two-way synchronization. Now, local changes (new files and edits) will be synchronized to the cloud.
