Website / Ready Tool/ Editor (windows) for 7 digits?

Hi,

I am trying to create my own wordlist and wondering if by now someone was able to find a website like textmechanic.com/Generate-List-of-Numbers.html
but able to generate 7 digits? it is perfect but 6 is not enough...

OR

If not I have the 8 digit list, is there a windows program that can handle that size and provide good editing options? I will need to cut out the needed list by removing first digit and taking the first 1/8 of the list, correct ? then I will need to add a prefix to it so it could be a 10 digit list with 3 fixed digits.

Notepad++ does not open it
notepad does not work
wordpad opens it but freeze and not good at editing

OR

Any windows generator that can handle the above goal and already tested ? (prefix and 7 digits)

Thanks

Ok so I found a tool that works under Windows to generate wordlists, I ordered it to generate 1234-XXXXXX & 123-XXXXXXX wordlists where 123 & 1234 are fixed operator numbers and XXXXXX & XXXXXXX are possible numbers from 1-999999 and 1-9999999

List 1234-XXXXXX was 10MB, List 123-XXXXXXX was 104MB

I tried 2 things, first chose windows file type for saving and then Unix files type, and I guess Unix works also for Linux in this case ???

So the sample line for Unix was:

1234000000
1234000001
1234000002
1234000003
1234000004
1234000005
1234000006
1234000007

Well I copied it as it was in windows but expanded into separate lines here.

This is how it looked under windows:




I copied the files/s to a new USB (different from Live USB) formatted as FAT32.

I booted Xiaopan 4.4

I used mount tool to load the new USB that has the file 1234XXXXXX.txt in root alone (Unix file type)

I loaded minidwep-gtk (Xiaopan 4.4)

I tried to load the file through dictionary tab but got an error that goes like : can't find cap file and followed by another error.

Any idea what I am doing wrong here, any commend about what I did ?
