About this i don't have a screenshot but i'll try to explain very well what happens. Sometimes i have generate a big pool of strategie moved on retest, retested by adding oos, at the end of this process i would like to save the strategies inside a folder over my hdd, so i select all and click over "save in sq4 format" appears a red messagebox (on the low right) that sais that doesn't exist a folder, so i'll go inside the SQ4 folder to copy manually the strategies and i found that the strategies are slowly disappearing by autodeleting, and at the end more or less 30 strategies (over 10k) remains inside the sq4 folder...
