Java.nio.file - Copying files

You can't copy a folder, thats why it generates an exception (you are trying to copy a folder using a copy file function).
You probably need to list all the files inside that folder and copy one by one

Issue was the above, so thanks temp02.

 

windows 10 deleted my desktop files

Step 1 - I upgraded to Win 10 and lost all my files on Desktop.

Step 2 - Found the files in Network - USers- Desktop

copied all files again to desktop.

Step 3- Restarted my machine again and lost desktop files again.

Step 4 - As suggested did the following as listed below but dont find my files.

• Press “Windows + E”, open This PC/Computer
• Open Local Disc C, open Windows.old
• Click on Users, select your User name
• Go to desktop folder

Cant find my files. Why is Win 10 deleted files again and again from Desktop ?.
