plz help

[Manichean]

There's a limit as to how long path and file names can be in Windows. I don't remember the exact length, but the path that throws the error is longer. Try renaming the file (change the title if it is within the Calibre library).

[kovidgoyal]

Those filenames are inside the chm, renaming it wont help. Basically you're only option is to convert it on OS X or linux.

thanks a lot kovid will give it a try

[foreverstud]

well finally i did find a way for my windows machine

decompiled chm file using html help workshop

that gae me a bunch of folders with .hhc file and .hhk file

converted hhc file to html using hhctohtml utility

that again gave me a list of files which linked to the chapters

merged all these files using snowsoft merger

now i get a merged html file containing links to all my chapers

finally loaded this into calibre and hmmmm rest is easy
