Canceling NTFS resize

Hi all,

I've started the resize (decrease size) of a 1300Gb NTFS filesystem to 1000Gb.
The process is in the "Quick data moving" stage and I'm worrying about the time it seems to take to complete.
"Overall percentage" says 1% and "Time remaining" 19:29:33 (but it's long time these values don't change).

I don't know if I can wait the normal end of the process and I see the "Cancel" button in bottom right corner ...

I'm going loosing all my data pressing that button?
Please help me !!!

Many thanks

 

My problem is the same, but i started a primary to logical partition conversion, and at this speed it seems that it will take 9 days!
I want to cancel but i don't know if it tries to rollback the operation, or just leaves me with an 1.4TB unallocated garbage partition :/ (it was full).
Please somebody answer to this! Should i press yes after the cancel or no?

 

plz do not cancel it if it is on the process of resizing, it may cause data loss. Be careful. Contact Paragon Support.
