I have amassed a very large ebook library over the years - about 90,000 books - up to 160,000 if you include duplicate formats.
My PC is on its last legs and I'm trying to transfer the library to a new PC. The old one is Windows 7 the new one Windows 10.
After quite a few export errors due to memory out fails, I managed to transfer 253 data files to the new PC. When I try to import I get the error message calibre, version 3.17.0
ERROR: Not valid: The folder E:\Programs\Calibre\Calibre Library is not valid: The exported data in part-0211.calibre-data is not valid, version (1819501834) is higher than maximum supported version. You might need to upgrade calibre first.
Traceback (most recent call last):
File "site-packages\calibre\gui2\dialogs\exim.py", line 257, in select_import_folder
File "site-packages\calibre\utils\exim.py", line 256, in __init__
ValueError: The exported data in part-0211.calibre-data is not valid, version (1819501834) is higher than maximum supported version. You might need to upgrade calibre first.
Both PCs have 3.17.0.
Can anybody help? I'm starting to cry.
Thanks
Booker
