# Folders visible on flash drive, but no files

data-recoveryusb-flash-drive

For no apparent or obvious reason, the files of my usb-flashdisk (32gb) are not visible/gone.

The drive is located, I get an 'autoplay' dialogue and all the folders are visible, but all the files (photo's, documents, .rar's, everything) is not visible (or gone…)
The folders show no contents, and the properties also show 0 bytes. The drive itself, on the other hand, shows that roughly half of the space is used.

I tried several usb ports and different pc's, but there is no difference.

What is the next step?
