What is

...

FDR is the expected proportion of false discoveries among all discoveries. FDR Step-up is a particular method to keep FDR under a given level, alpha, that was proposed in this paperIn Partek Flow, if one calls all of the features with p-values 0.02 or less, the FDR is less or equal to 0.41.

What is fold change?

In Partek Flow, fold change is in linear scale (even the input data is in log scale). It is converted from ratio, which is the LSmean of group one divided by LSmean of group two in your comparison. When ratio is greater than 1, fold change is identical to ratio; when ratio is less than 1, fold change is -1/ratio. There is no fold change value between -1 to 1. When ratio/fold change is 1, it means no change between the two groups.
