Hi Igor,
Ed's clsheap.prg file can be found in the downloads section, it is file # 9482.

>Hello Tracy,
>thank you for response, appreciate that. Well, I was able to hide the DOS window by adding another parameter to XCOPY command. Now there is another problem: the copying files takes about a minute or so, that's not bad but the problem is that this command will be issued from within FoxPro script and, it seems to me, that FoxPro script doesn't wait until all files are copied. Is there any way around that? See, I looked at the thread about API call and stuff. First of all, it's a little confusing for me, never used them, don't even know where to start. I tried to use the sample code but it can't find the "CLSHEAP" procedure in the line "SET PROCEDURE TO CLSHEAP ADDITIVE". I have no idea where to find it. Some Files section. Where is it?
