I've imported 35.796 wma/mp3 files, no problem. The last couple of days I'd tried to update my library, with another 15.000 music files, about 8.000 video files and 15.000 approx. jpeg's from my digicam. Some files are new, many have been imported before (I changed some folders after rearranging the files). The program searches for these files in a very slow way (since CPU goes to 100 % and virtually blocks the working of my pc). When it found all files, it started to import, and stopped after 387. I retried, then it stopped after 1 file. I'm trying to import just one folder, this is ok. So why could I import 35.796 files in no problem (couple of hours indeed), but am I facing a failure when updating my library? Thanks for your help, I really appreciate these forum!
