I was uploading two files of 5GO each, and after 1h i wanted to check something and i click on the desktop icon, like dropbox to see the files.
And the upload stop, and the software erase completly my 10G0 files ..... !!!! and start to download my 300MB files.
So hoppeeefuuullyyyy i had my windows 8 backup system, however i had lost my files, because i cut and paste it.
My config is windows 8 64bits.
Thanks for your work !
