Running a force wipe on a file will basically make XL Delete ignore any other
process that has the file open and wipe the file. This method can be used for
wiping "index.dat" files or other files that may need to be wiped but are being
used by another program.
To force wipe a file:
Choose "Force Wipe" from the Tools menu.
OR
Choose the "Force Wipe" icon from the toolbar.
Then simply browse for the file to force wipe.
NOTE: Not every file can be force wiped. This feature was designed for
Index.dat files and other files that are not being accessed exclusively. System
files and other files being used by Windows or exclusively by other programs can
not be force wiped.
