Windows 11 Data lost and corrupted upgrading to windows 11

[sharad2210]

I have lost all my personal data and some python files are corrupted during upgradation from windows 10 to windows 11? Is their any way to retrieve all the data? i have tried everything on google but none seems to be working´? any ideas or suggestion for retrieving data would be helpful? thanks in advance.

PS:.python files are important for me to recover.

where was the personal data stored before the upgrade i.e, was in on the old C drive ?
does your new C drive have a folder called Windows old?
how long has it been since the upgrade... If you have been running this system for more than a few days after the upgrade then the odds of recovery are very slim
