I use 7-zip to create several archives with fixed size (512 Mb) from one big file. And they have strcuture:
my_name.zip.001
my_name.zip.002
...
my_name.zip.005
My problem is that without 7-zip I can't open them, is it possible by just using Windows 7 default tools?

On Windows 7:
copy my_name.zip.* my_name.zip /b /v /y and press EnterThis is beacuse 7-Zip doesn't split zip files according to the ZIP specification, but simply splits the binary file into smaller files, just like the GNU/Linux command split. xcopy stuff.* stuff will convert all the stuff.001, stuff.002... back into the original file.

several archives with fixed size (512 Mb) from from one big file My experience at Windows 7 is, that the on board unzipper runs in ressource problems or internal errors with such big files. – marsh-wiggle – 2016-06-29T11:14:01.943
Did you try it? It just copy all my_name.zip.00X to the same my_name.zip file (rewriting). – mrgloom – 2016-06-29T12:08:43.123
My bad, I gave you the wrong command. You should use copy instead of xcopy. – Nathan.Eilisha Shiraini – 2016-06-29T12:35:23.953
Still not working. – mrgloom – 2016-06-29T12:51:10.953
Well now you surpirse me. Try adding /b /v /y after the command, to tell Windows you're using a binary file. If I remember correctly these are the switches I use when joining together archive files splitted with GNU-split. – Nathan.Eilisha Shiraini – 2016-06-29T13:01:10.973
And I am sure 7-zip uses GNU-split style to make multifile ZIPs, because I found that on their official website when I tried opening a multifile ZIP made with Linux zip command. – Nathan.Eilisha Shiraini – 2016-06-29T13:02:27.863
1In windows 10 at least the command needs to be slightly different. The parameters need to be IN FRONT of the source. Thus copy /b /v /y my_name.zip.* my_name.zip – Thomas – 2019-05-08T12:08:27.173

Sure!
Windows has a default zip uncompresser. Just right click on the file and unzip. But if this doesn't work, you can always download Winrar. The procces is the same, right click on the file and click on the unzip option with winrar logo

1I think the problem is that the zip file is split into parts. Not sure if the default windows unzip can handle that. – jiggunjer – 2016-06-29T09:24:21.767
I does! Just select all of them and click the unzip option. – kek – 2016-06-29T10:09:14.273
I can't see any menu on right click for default windows unzip. – mrgloom – 2016-06-29T12:09:49.803
Maybe extract? I do have it in other language so I dont know the exact english name – kek – 2016-06-30T09:33:52.720
If you only don't want to install the gui you can use the commandline version (http://www.7-zip.org/download.html) or google for "7zip portable version"
