paritial file copy

Author	Message
jon #1 / 5	paritial file copy i want to create a smaller file from a larger file. In other words, I like to extract a smaller portion of a media file from the original one. Is there a way? I try to copy the file to another path and then cancelling it before its complete, however, the partial copy file did not appear.

Klaus H. Probs #2 / 5	paritial file copy There is no API that will copy only part of a file (and as you found out, canceling a copy will rewind the whole thing). You need to open the file, read what you need to read and then write it out to the target file. -- . . . . . . . . . . . . . . . . . . . . . . Klaus H.

Russell Kinas #4 / 5	paritial file copy ummm..... dim intFF as integer 'for freefile dim mystring as string mystring = string(2000)'the number is where you should put how much of the file you want(bytes) intFF = FreeFile open "File.exe" for binary as intFF get #intFF, , mystring close intFF intFF = FreeFile open "OutputFile.exe" for binary as intFF put #intFF, ,mystring close intFF this works for me.....just replace file.exe with the file you want to get part of and outputfile.exe with the file you want to put the new stuff in in this example 2000 is how many bytes you want to get from the file hope this helps, Russell Kinasz =)
