I am trying to import contacts from micro-SD to (non Android) Nokia phone. So I first exported current contacts on micro-SD card in hope that i will be able to modify the exported file and then import it.

Exported file type is Nokia backup file .NBF. it seem it is actually an ordinary zip file.

I can unzip exported .NBF file and modify it (contacts are stored in .vcf - vcard).

However when I zip it and try to import it the phone says file is corrupted.

 

i checked zip files with zipinfo:

Unmodified file:

$ zipinfo Backup001.NBF Archive: Backup001.NBF Zip file size: 3031 bytes, number of entries: 10 -rw-a-- 0.0 fat 1160 b- stor 20-Mar-30 11:31 predefhiddenfolder/predefisasettings/usersettings/user_settings.wbxml dr-x-hs 0.0 fat 0 b- stor 10-Jan-01 00:00 predefhiddenfolder/predefisasettings/usersettings dr-xahs 0.0 fat 0 b- stor 07-Jan-01 00:00 predefhiddenfolder/predefisasettings dr-xahs 0.0 fat 0 b- stor 07-Jan-01 00:00 predefhiddenfolder -rw-a-- 0.0 fat 214 b- defN 20-Mar-30 11:31 predefhiddenfolder/backup/WIP/F01 drwxa-- 0.0 fat 0 b- defN 20-Mar-30 11:31 predefhiddenfolder/backup/WIP drwxa-- 0.0 fat 0 b- defN 10-Jan-01 00:00 predefhiddenfolder/backup -rw-a-- 0.0 fat 256 b- defN 20-Mar-30 11:31 predefhiddenfolder/backup/WIP/32/contacts/1.vcf drwxa-- 0.0 fat 0 b- defN 20-Mar-30 11:31 predefhiddenfolder/backup/WIP/32/contacts drwxa-- 0.0 fat 0 b- defN 20-Mar-30 11:31 predefhiddenfolder/backup/WIP/32 10 files, 1630 bytes uncompressed, 1409 bytes compressed: 13.6%

then i modify 1.vcf and update Backup001.NBF with:

zip Backup001.NBF -f -r predefhiddenfolder/backup/WIP/32/contacts/1.vcf

Modified:

$ zipinfo Backup001.NBF Archive: Backup001.NBF Zip file size: 2958 bytes, number of entries: 10 -rw-a-- 0.0 fat 1160 b- stor 20-Mar-30 11:31 predefhiddenfolder/predefisasettings/usersettings/user_settings.wbxml dr-x-hs 0.0 fat 0 b- stor 10-Jan-01 00:00 predefhiddenfolder/predefisasettings/usersettings dr-xahs 0.0 fat 0 b- stor 07-Jan-01 00:00 predefhiddenfolder/predefisasettings dr-xahs 0.0 fat 0 b- stor 07-Jan-01 00:00 predefhiddenfolder -rw-a-- 0.0 fat 214 b- defN 20-Mar-30 11:31 predefhiddenfolder/backup/WIP/F01 drwxa-- 0.0 fat 0 b- defN 20-Mar-30 11:31 predefhiddenfolder/backup/WIP drwxa-- 0.0 fat 0 b- defN 10-Jan-01 00:00 predefhiddenfolder/backup -rw-r--r-- 3.0 unx 208 tx defN 20-Apr-03 01:04 predefhiddenfolder/backup/WIP/32/contacts/1.vcf drwxa-- 0.0 fat 0 b- defN 20-Mar-30 11:31 predefhiddenfolder/backup/WIP/32/contacts drwxa-- 0.0 fat 0 b- defN 20-Mar-30 11:31 predefhiddenfolder/backup/WIP/32 10 files, 1582 bytes uncompressed, 1366 bytes compressed: 13.7%

in this line: -rw-r--r-- 3.0 unx 208 tx defN 20-Apr-03 01:04 predefhiddenfolder/backup/WIP/32/contacts/1.vcf it says that format is 3.0 unx.

is there any way to zip it so format will be 0.0 fat?

 

Edit: added some clarification

Edit: I tried using -k flag as sugessted by @FennecTECH

it looks better but still doesn't work.

$ zipinfo Backup000.NBF Archive: Backup000.NBF Zip file size: 2501 bytes, number of entries: 10 drwx--- 2.0 fat 0 bx stor 20-Apr-03 00:37 PREDEFHI/ drwx--- 2.0 fat 0 bx stor 20-Apr-03 00:36 PREDEFHI/PREDEFIS/ drwx--- 2.0 fat 0 bx stor 20-Apr-03 00:36 PREDEFHI/PREDEFIS/USERSETT/ -rw---- 2.0 fat 1160 bx defN 20-Mar-30 11:31 PREDEFHI/PREDEFIS/USERSETT/USER_SET.WBX drwx--- 2.0 fat 0 bx stor 20-Apr-03 00:37 PREDEFHI/BACKUP/ drwx--- 2.0 fat 0 bx stor 20-Apr-03 00:37 PREDEFHI/BACKUP/WIP/ drwx--- 2.0 fat 0 bx stor 20-Apr-03 00:37 PREDEFHI/BACKUP/WIP/32/ drwx--- 2.0 fat 0 bx stor 20-Apr-03 01:04 PREDEFHI/BACKUP/WIP/32/CONTACTS/ -rw---- 2.0 fat 208 tx defN 20-Apr-03 01:04 PREDEFHI/BACKUP/WIP/32/CONTACTS/1.VCF -rw---- 2.0 fat 214 bx defN 20-Mar-30 11:31 PREDEFHI/BACKUP/WIP/F01

  • Hi. I'm not sure this question is about Linux. Nokia phones are not Linux systems, as far as I am aware. Perhaps try on Superuser Stack Exchange? Commented Apr 3, 2020 at 1:55
  • But the zip tool the OP uses is a Unix tool. It is a question about zip usage, AFAIU Commented Apr 5, 2020 at 15:08

You can do this with Go:

package main import ( "archive/zip" "io" "os" ) const creatorFAT = 0 func main() { // in file, _ := os.Open("in.txt") info, _ := file.Stat() head, _ := zip.FileInfoHeader(info) // default is Unix head.CreatorVersion = creatorFAT // out zipfile, _ := os.Create("out.zip") archive := zip.NewWriter(zipfile) // write writer, _ := archive.CreateHeader(head) io.Copy(writer, file) archive.Close() }

Result:

$ zipinfo out.zip Archive: out.zip Zip file size: 151 bytes, number of entries: 1 -rw-rw-rw- 2.0 fat 7 bX stor 20-Apr-02 19:54 in.txt 1 file, 7 bytes uncompressed, 7 bytes compressed: 0.0%

You’ll need to unzip the folder. Then re zip it with the -k option This will get you 2.0 fat. I don't know if this will work but its worth a try. You will need to do it with the command line.

I think the problem is with the user_settings.wbxml file Certain things are supposed to be updated there, probably according to the size of the file or the number of contacts

Let me present my powerful tool that does this automagically https://github.com/pas-calc/nokia-contacts

You might adjust this script to your needs. For python related, you shall stick to from zipfile import ZipFile.
