I have corrupted data on my USB Flash Drive and the PC will not allow me to delete these files. What can I do?

This can occur if the file allocation table (FAT) has become corrupt in some way (e.g. loss of power etc).

The drive can be formatted to remove the problem.

Formatting the drive can erase all data. If you have any data on there it is advisable to retrieve it first on your computer. You may need to use file recovery software before formatting.
