[SOLVED] Is downsizing persistent.dat possible?
It is now possible to extend persistent dat file by using sudo sh  datfile extend_size_mb (see 5. Extend persistent dat file here).

For example:

sudo sh  persistent.dat 2048

"That means extend persistent.dat by 2048MB (+2GB), if the old size is 1GB, then it will grow to 3GB after you extend it."

My question is: Is it possible to do the opposite? Downsize persistent.dat?...

Example: Assuming I have a 96GB persistent.dat file, I want to resize to 64GB (65536MB). Can I issue the command below?

sudo sh  persistent.dat -32768

So that, in the end, I'd get a persistent dat file reduced to 64GB (65536MB).
