When uploading your data we can ensure that the files are permanently kept on the usb. Anyone who receives the usb will not be able to delete the files. They will however be able to use the remaining space available on the usb freely for storage. This process must be done at the point of manufacture.
We simply take the data you want secured on the usb and partition the drive so a portion of the usb's memory is dedicated to your files and the remaining portion is freely accessible.
Permanent USB Files are another reason why USB Direct are the USB Professionals.
