Re^2: Fast way to compare two picture-files

Depending on what the OP is asking for, checking ~~the first 16K of~~ the file won't provide the correct answer if a) the OP is trying to determine are the images the same (rather than just are the files identical) and b) the files are in different formats (say, JPG and BMP) but are actually the same image.

Update Oops -- ikegami is quite right, the loop checks the entire file, not just the first 16K.

The code checks the entire file (not just the first 16K). "`for (;;)`" can be read as "for ever". And the post already says the code compares files not images.	[reply] [d/l]
