The process cannot access the file '...' because it is being used by another process.

This usually happens when the output is xlsx or sdltb. Less frequently it also occurs with xlsx as an input format. In principle, though, can happen with any file type.

The message is quite self explanatory: if you want write to a termbase, and it is already open in MultiTerm, the conversion fails. Likewise for Excel and xlsx files, and possibly with any file that is open in any applictation.

If you're not aware of any file that may indicate a zombie process locking the file, for example after an earlier crash. The easiest way to resolve that is a Windows reboot..
