Importing File Issue

[NickBel]

Hi,

While trying to import my files, I get the below error.

calibre, version 7.15.0
ERROR: Not valid: The folder C:\Users\nicho\Personal Documents\Files Storage\Calibre Data\OneDrive-2024-01-10 is not valid: The last part of this exported data set is missing

Traceback (most recent call last):
File "calibre\gui2\dialogs\exim.py", line 280, in select_import_folder
File "calibre\utils\exim.py", line 392, in __init__
ValueError: The last part of this exported data set is missing


I have no way to redo the export, I don't have those files anymore. Is there a solution, even to recover the files partially? There seems to be 1 part missing, but even if I could recover the files contained in the other parts of the exported data, it would be better than nothing.
