quickbms supports the comtype bpe_compress which is just the recompression algorithm of comtype bpe (the known version of Philip Gage).
So if that's the algorithm you are looking for:

Code:

comtype bpe_compress
get SIZE asize
clog "new_file.bpe" 0 SIZE SIZE

As I told you, the comtype to use is bpe_compress.
The following is a full script for creating a compressed file with the same format:

Code:

comtype bpe_compress
get SIZE asize
clog MEMORY_FILE2 0 SIZE SIZE
get ZSIZE asize MEMORY_FILE2
log MEMORY_FILE 0 0
put SIZE long MEMORY_FILE
put ZSIZE long MEMORY_FILE
append
log MEMORY_FILE 0 ZSIZE MEMORY_FILE2
append
get SIZE asize MEMORY_FILE
get NAME filename
string NAME   ".compressed"
log NAME 0 SIZE MEMORY_FILE

I used that script an works. Thanks you very much for your help.

Is there a source code for bpe_compress and bpe (for uncompress) ?

decompress: http://www.csse.monash.edu.au/cluster/R ... ress/bpd.c
compress: http://www.csse.monash.edu.au/cluster/R ... ress/bpe.c

If you prefer the code that uses the memory instead of file then check src\compression\bpd.c and src\compression\bpe.c in the source code of quickbms: http://aluigi.org/papers/quickbms_src.zip

Sorry, I did not get it. How would a script be built to unzip these files?

Thanks for leaving the compression script =D

comtype bpe_compress
get SIZE asize
clog MEMORY_FILE2 0 SIZE SIZE
get ZSIZE asize MEMORY_FILE2
log MEMORY_FILE 0 0
put SIZE long MEMORY_FILE
put ZSIZE long MEMORY_FILE
append
log MEMORY_FILE 0 ZSIZE MEMORY_FILE2
append
get SIZE asize MEMORY_FILE
get NAME filename
log NAME 0 SIZE MEMORY_FILE
