DropBox is an free online file synchronization utility.
It creates a new folder on your disk and all the files in that folder will be automatically synchronized with your online "DropBox" account. Thus, you are not obliged to carry your files on a flash disk. In addition, you can access to them wherever you are and at any time. You only have to drag your photos, documents, texts and any file into the folder. It is also possible to use the context menu to put a file in the folder.
