Opening MOBI format

[seas]

I'm new on this forum, and first time user of e-book reader. I buy Kobo eReader Touch few days ago, and I have a problem. I have some e-books on my computer, around 100 of them, and they are all in MOBI format. I load this books on my new reader and I'm able to open them, but big part of the text is just a some strange leters trown in without any meaning. Let's say that 40 % of text is like that, just leters and simbols without any meaning. the rest is OK.
What causing this problem?
I have Kindle e-book reader app instaled on my computer, and I can open and read all this books without problem on my computer, but not on my new KOBO

Thank you in advance

You need to use Calibre which is a free download. You can convert your MOBI files to EPUB very easy.

Michael...
Is that to say then, that .mobi files will not go into my Nook tablet the same way you explained how to get epub books into my Nook?
It was easy to drag and drop a trilogy of epub books into Nook when I opened it on my computer, found my "Books" folder and dropped them in there.
It definitely will not work the same way with .mobi book extensions?
(I will download Caliber if necessary, but did not need to with epub files)
Thanks much
