Hello
i heard that google email ( gmail ) can be used for that prupose
first of all google email is about 7GB space
if you register a google email something like yournameATgmailDOTcom
then go and start a new message , attach the files you want to it then save it as draft ( a copy for later use )
then when you are in a different place , like office , or another town , you can open that email (gmail) and go to drafts folder and download it
please note , the attachment size limit maybe up to 20MB (not sure ) , so you may need to use small files or break your big files with winrar into small files or you maybe able to do it using another software
please remember , that some sharing website can keep your files saved for a month for free , but limited size and plulic access to them is the problem here
you may also use free hosting space , which is provided by hosting companies such as geocities from yahoo , but this is also have a limit of file extension as well as size
i hope this can help
thank you
