I was hoping someone had written some file deleting in C and knew why it would be faster and able to kill more files than my Java code. The C program I have been referring to is called Ace Utilities. Back in the 16 bit days I had ways of tracing any code to find out how they pulled off their magic. But I have no such tool for 32 or 64 bit code and presumably programs now are so huge it would be quite hard to find the code of interest. The hope was, perhaps with a bit of JNI, I could pull off c-speed and power. I guess it may have something to do with ownership, and somehow overriding that ownership to kill files, or possibly overriding in-use. -- Roedy Green Canadian Mind Products http://mindprod.com To err is human, but to really foul things up requires a computer. ~ Farmer's Almanac It is breathtaking how a misplaced comma in a computer program can shred megabytes of data in seconds.
