Is there a way to merge multiple part files (.0001, .0002, etc.) from multiple drives?

I have three part files of 5 GB each, but I have only 20 GB on the hard drive. I would need another 10 GB to accomodate three-part files and the merged file. I'm planning to have two-part files on a flash drive and one on a hard drive so that there is enough space to merge them.

I'm using 7-Zip to do this.

If the split files are .part1.rar , .part2.rar (use WinRAR), as WinRAR allows you to do this. WinRAR will detect the missing files and ask you to select the folder with those missing files.

But with .001, 002, I don't even know who made these type of file.

There are many programs can join / merge these files, but not like WinRAR.

If you really need to join these files, contact the person who "invented" *.001, *.002, but I don't think that's possible, so you could buy a new hard drive, or delete some data in your drive, sorry.

But, why do you only have 20 GB in your hard drive, that's too small! :D

.001 etc are common (older) extensions for (among other things) .rar files – AndrejaKo Jan 4 '12 at 5:20
I tried WinRar and it works like a champ! Thanks for the help!! I have only 20GB free in my 750 GB hard drive :) – smh0427 Jan 6 '12 at 22:10

To join files with *.001 *.002 extention you should use FFSJ: The Fastest File Splitter and Joiner.
