My C: drive crashed, and I need to reinstall calibre.
1) I would like to use a non-standard drive to install it (my "T" drive), that links to my micro$oft one-drive storage.

2) I did (once) create a backup in calibre, but have no idea where it is and what the file name would be.

3) I would also like to customize the library location, and hopefully find all of the calibre files I have on the machine (perhaps in different drives).

4) I would also like to be able to change my library location so it will also be found by my one-drive software for future backups!

currently running win 10/64 bit

thanks for your suggestions and help in advance
