I always wondered about something in barf.exe. As far as I understand it it increases the filename all the time, right? What happens when it reaches the max filename length (Which I believe is 255 characters)?

I also tried barf2.exe and it compressed book1bwt nicely to 0 bytes But when I tried c100 or c1000 or c1000000, nothing happened. The output was exactly the same. Or is that the joke?

EDIT: Argh, barf.exe isn't increasing the filename, it's increasing the extension...

EDIT: Actually, there can only be one extension so you're still increasing the filename

What happens when it reaches the max filename length

it will fail. but Universe will be finshed much earlier just compare 255²⁵⁵ filenames with 10¹⁰ years

It's possible also to write compressed data to hidden alternative stream of the file on NTFS, why not?

Actually, as every recursion appends 4 bytes (.x[0-9][a-z]) to the extension, it's somewhere around 63²⁵⁵, but still much bigger than 10¹⁰ indeed

Also, the Windows API has the bad habit to limit path+filename to 260 chars (see this MSDN article), but there are workarounds and it's not a limit of NTFS. Still, it's annoying for "C:\My old harddisk backup\Drive X\My wonderful programs\The best programs I ever had\Huh installing or extracting things wont work in here\Some Java or open source program that extensively uses directories with long names\" cases
