Edit symlinked files in Dropbox I have a soft symlink between the Documents folder on my main computer and a folder in Dropbox, say dbDocs. If I now edit a document, say thesis.tex, in dbDocs from another computer, will the symlink on my main computer see that thesis.tex has changed and sync this file back to Documents? Or will the symlink just overwrite the newly edited file in dbDocs with the corresponding file from Documents?
The quick answer is that if you open Documents/thesis.tex after editing it in your Dropbox folder on another computer, you will see the changes. As @Mark said in a comment, a symlink is simply a pointer to another location on your computer. If that other location has its contents changed, those changes will be visible when using the symlink in Documents, just as they would if you examined the file directly in the Dropbox folder.
