I'm currently trying to run portable calibre off of an external HD while one of my laptops is out for repairs. It doesn't want to open where I currently have the folder saved due to the file path being too long. Now I recall having this problem once before, but was able to fix it after shortening some folder names. However, it seems like the character limit is less than it used to be? I don't recall what it was before, but now it's telling me it has to be less than 59 characters. This seems very prohibitively short.

My laptop backups are meant to closely mirror the file structure of the laptop to make backups simple and easy and so I can easily find things on the backup. Of course there are extra folders in the path because I have more than one backup on the external HD. I have made some adjustments to folder names again where I feel able to, but the path name is still too long.

I don't understand why the character limit was shortened. Does this have to do with the fact that the backup was done on a windows 10 device and I'm trying to run it from the external HD on a windows 8 device now? Does this have anything to do with the version of Calibre I'm running? I haven't updated in awhile so I'm running Calibre 4.13. The version I was using the last time I tried running this from an external HD was 3.39.1.

Thanks in advance for your help.
