Windows: folder or file open in another program

When you try to move a folder:

    "The action can't be completed because the folder or a file in it is open in another program"

This stunningly unhelpful error message has persisted through many versions of Windows.

The way I work around it is:

• Rename an unrelated file or folder nearby, then rename it back again.
• The original folder or file should now be "unlocked"

You can always reboot to fix it, too.

How to transfer files between Windows 7 and Android 4

Settings | Storage | (three dots in top-right) | USB computer connection | Camera (PTP)

Then go to Developer Options (read elsewhere how to get this), and tick 'USB debugging'.

Voila - your device will appear in My Computer | Portable Devices.

Copy the files to a subdirectory of the Android Camera device in Windows, and move them into the right place from within Android. e.g. using ES File Explorer

Move directory on FTP server

without downloading and re-uploading:

rnfr source_dir
rnto target_dir
