Default ftree file from stage 2 overloads trash in Colab

Started testing 30.9 b1 on a couple of Colab instances on 13M PRP-CF exponents (10 curves, B1=50000, B2=15000000) and noticed soon a large <exp>.ftree file (~1.2GB) during stage 2 of each curve.

When stage 2 is completed, the <exp>.ftree file gets deleted and moved to the Trash folder - exhausting soon the 15GB space limit. Once proper debugging is done, would it be possible to truncate that file to zero- or minimal-length, prior to deletion?

Good suggestion.

In the meantime, set EcmSaveFtreeToDisk=0 in prime.txt
