F1 2015 ERP archives

It's an interesting file format and currently F12015 uses both version 2 and 3.

In reimport mode quickbms will display all the files that get reimported, something like "> OFFSET SIZE FILENAME". Do you see your edited file in this list?
Maybe check again the section 3 of quickbms.txt, you have to make the exact steps you did for the extraction to allow quickbms to import the files.

Thanks for your help tried step by step still wont take the BMS file has 4 bits in first line of file of (BXML) instead of (ERPK) and it is these 4 bits that don't match says BMS when reimporting I tried to change BXML to ERPK but then it comes up with another fault -: (last script line before the error:
11 get files long)

What does this mean beats me thanks for your help Chris.

this is the exact message that comes up

signature of 4 bytes at offset 0x00000000 doesn't match the one expected by the script.

This one "OBMX"
01 42 58 4d .BXM



expected: "ERPK"
45 52 50 4b ERPK

It seems you are using the reimport feature in the wrong way.
I give you an example:

Extraction:
- launch quickbms.exe
- select f12015_erp.bms
- select the ERP file to extract
- select the output folder

Edit the extracted files you want to reimport WITHOUT changing their location.
Delete those that weren't changed.

Reimporting
- launch reimport.bat
- SELECT THE SAME SCRIPT, ERP ARCHIVE AND FOLDER YOU SELECTED FOR THE EXTRACTION

Do you mean viewing and editing the extracted files or reimporting them back into the erp archive?

Reimporting should work correctly.
Personally I can't help with the content of the extracted files but maybe other users can.
