My apologies if this FAQ but I did search.

My family has 3 eBookWise 1150's and 9000 books in many formats. Calibre is letting me organize and remove duplicates BUT....

I'm slowly converting everything to ePub for the future and getting rid of old formats starting with the most wasteful (size). Since Calibre does not support either the 1150 nor conversion to imp, I need to convert externally using mostly Book Designer and store both formats.

If Calibre supported my device it would apparently take care of this automatically but it doesn't so I need to be able to sort on format: "Show me only books present in imp". These can then be "Save to disk" to the flash card reader/writer that my family is familiar with from their digital music players. It will also help with the conversion to ePub i.e. "Show me all txt files" so I can convert them.

I suppose I could export (copy) all imp to another directory and use another program to manage them but I would still have to keep them in Calibre to maintain order meaning two copies of every imp. Wasteful, especially for backup and I'm not that happy about staying current with any more software than I have to. This isn't my occupation.

It doesn't help with the format conversion either.

Can't be all that hard to do, can it?
