What sort of files are your talking about?

[bubba_damage]

im wanting to idenify files by the "file header" (useing quick + binary object
to open a portion of a file, flv or a mp3, video ect.) without having to load the extire file into memory.

what for?
in the firefox cache files are unnamed and there for i can find the file extension at the files header.

(in anycase which i have trouble idenifying because each file header is unique, starting at differant bytes
one way is to compare like these 2 examples of a JPG and a GIF

files are loaded from byte array oject and use string parser object to transform into ASCII into edit object
here is the first 14 bytes of each file (inlcuding the 0 byte)

÷

but it doesnt cut it because of differant settings change the bytes so maybe start at and end at bytes?
------^^^^
ÿØÿàJFIF

H

code:
compare two general values

chr$( "String Parser", getbyteat( "ByteArray", 6))+chr$( "String Parser", getbyteat( "ByteArray", 7))+chr$( "String Parser", getbyteat( "ByteArray", 8))+chr$( "String Parser", getbyteat( "ByteArray", 9))+chr$( "String Parser", getbyteat( "ByteArray", 10))

Equal

"JFIF"

and

code:
compare two general values
chr$( "String Parser", getbyteat( "ByteArray", 0))+chr$( "String Parser", getbyteat( "ByteArray", 1))+chr$( "String Parser", getbyteat( "ByteArray", 2))

equal

"GIF"

good code but
am i on the right track? )


thankyou.
