Yes. It is possible to recover only one file or a few files. Data Recovery doesn’t mean that whole of the data stored in your media must be restored. However, it is notable that sometimes, the cost of data recovery of a single file may seem to be a little high due to the fact that for the recovery of that single file whole system may be required to be analyzed. It depends upon the type of file you are looking for. Moreover, it is also important on your part to check whether the file you want to recover can be re-created within short period of time. If you can create it in a few minutes or hours, you probably won’t need to recover it. So, it’s completely your choice.
