Files with .MOB extension (not .mobi)

BartZorn · 02-28-2015, 06:44 AM

Hello,

I have a bunch of files, apparently MOBI files, which have a MS-DOS style file name, ending with .MOB.

When I drag such a file into calibre, it seems to be recognized as a mobi file, but its format is recorded as MOB, not MOBI.

When I try to import the whole lot via the Import books button, the files are not recognized.

Renaming all files is just a little bit too much. Is there another way to do it?

TIA,

Bart

You can rename them in bulk, using one of several methods including the command prompt.

Thank you for your advice.

I already tried to bulk rename the files, using the freeware Bulk Rename Utility. However, I did not find a way to change the file name extensions with this program.

A new search for bulk rename utilities brought me to Advanced renamer, http://www.advancedrenamer.com/ , also freeware, which did the trick.

Regards,

Bart

Sure thing.
IMO the easiest way is still "ren *.mob *.mobi"

But the Bulk Rename Utility has a box marked "extension" in the lower right quadrant. I am guessing that would do it.
It is a pretty cluttered interface I guess.

(I haven't used it, just seen the example pictures. I prefer regular expressions via the CLI.)

Yes, rename might help, but in Windows it is missing a -r option.

The extension option in Bulk Rename Utility seems not to do what you expect.

Advanced renamer does the trick.

Flash Renamer will change file extensions also. I've been using the program for years, it's one of the first things I install on a new system.
