Final answer:
Deleting files from a USB storage device marks them as deleted and the space as available, but they are not permanently removed immediately and can sometimes be recovered with data recovery tools.
Step-by-step explanation:
When you delete files from a removable storage device such as a USB storage device, the files are not immediately and permanently removed. Instead, the space that the files occupied is marked as available for new data. This means that, initially, the data still exists on the device and may be recoverable using data recovery tools. Over time, as new files are saved to the device, they can overwrite the deleted files, making recovery more difficult. When deleting files from a removable device, they are not moved to the computer's Recycle Bin or the device's own Recycle Bin; instead, they are simply marked as deleted in the device's file system.
