How do i unpack or use an avi.zip.001 file?

Question

I've never seen a file name like this before . . . with .001 at the end.

Answer 1

If this is a zipped file, it could be that the creator renamed it to make it easy to email (some programs do not allow .zip files to be opened)

Here's what I would try - just rename the file to avi001.zip

Then try opening it. In Windows this will start the Windows unzip wizard and you can follow it.

If the wizard does not start, then the file is probably not a standard .zip file, you might want to just delete it.

Next you could also try renaming it to 001.avi and hope that it is an uncompressed movie file, in which case, after renaming it, double clicking it will play it.

This assumes the file is from a trusted source, otherwise just delete it.
