Question about patching in files using SFK

[L33THAK0R]

Hi all,

Sorry to flood this board with questions but I'm honestly a bit stumped. I'm using this version of SFK to try and patch back in some files (Bink) that bloat the final output unless packed separate to their data archives. My current patching command (for use in a batch script) looks like:

sfk.exe partcopy INPUT_BINK 0 OUTPUT_ARCHIVE START_OFFSET -yes

However only a name less file, identical to the input bink video, with the start offset as its name, is produced. Although uneeded for my purposes, I tested extracting the file via SFK using:

sfk.exe partcopy INPUT_ARCHIVE -fromto START_OFFSET END_OFFSET OUTPUT_BINK -yes

I made sure to use the decimal rather than hexadecimal for calculating the offsets, and extraction was successful, however patching this file back in seems to be nigh impossible.
