I noticed that my settings in Site Manager disappeared after I updated FileZilla to 22.214.171.124. After further research, I noticed
* directory FileZilla was created under C:\Users\\AppData\Local and it has the image files similar to what I saw in Data\Cache
* setting XML's are in C:\Users\\AppDataRoaming\FileZilla
I wonder whether this is a bug or something changed in this new release?
