* doesn't exist, to prevent showing "about to overwrite" errors to the user.
* If you simply want to check for existence without downloading/uploading afterwards,
* then you should use sideIsSource=false.
*
* @param details selects the level of details we want.
* By default this is 2 (all details wanted, including modification time, size, etc.),
* setDetails(1) is used when deleting: we don't need all the information if it takes
* too much time, no need to follow symlinks etc.
