I had Skype on my Windows 7, and it had all chat-log for Skype. Then, I faced some Issues with the OS, so I deleted it and Installed Windows 8.1. I now have Skype Desktop on my PC, but It doesn't have chat log, and I am in need of all my old chat log. Is there any way to recover all my lost chat log?
Individual Skype conversations are stored in
%APPDATA%\Roaming\Skype\username\chatsync in a .DAT format. There is also a
\Skype\username\ which includes all of your Skype History.
If you deleted this folder during the reinstall, then it's likely you have lost the chatlogs.
