Hello Jeff, thank you for your help, but my problem is still the same ... I can open encosures in the adequate app and there I can save them , but the command Save enclosure as do not work ... maybe there can be a to long time to wait for it ?? in minutes ?? Before last upgrade of my W10 home 32 bit I save enclosures normal .. in real time .. :) Pavel
