I found a bat file inside a folder in L:\Calibre Portable\Calibre\app\resources\ made by itimpi. Is this still recommended to use? It has a different folder structure than the Calibre Portable

I would like to retain the folder structure so I can just overwrite it with a new version of Calibre.

The easiest way I can think of is to copy everything into the SSD and symlink the Calibre Library which contains the book

The problem is the metadata.db and a json file is inside the Calibre Library folder.

Can i change the metadata.db location by adding a command to the launcher similar to the batch file?

Thank you!
Putting symlink to an hdd resident library into the ssd resident Calibre Portable folder should be OK, but I am not sure if you can use the CALIBRE_OVERRIDE_DATABASE_PATH environment variable in Portable to 'redirect' the database location - I have a feeling you cannot.

If your SSD is an internal drive what's the point of installing Portable on it?

FWIW: I moved a 120K book library with a 300MB metadata.db from a WD Caviar Black HDD to my Samsung 500GB nVMe M2 SSD. The performance difference was negligible - start up times went from 8s to 5s, switching VM Views, VLs, bulk metadata edits were all much the same - after a couple of days i put it back on the HDD. Why would this be so - because for most operations calibre uses in in-memory copy of the database.
