Any database will make heavy use of RAM for caching and other performance reasons.

MyISAM caches index blocks in the key_buffer. Data blocks are left for the OS to cache.

The INDEX(es) are kept in the .MYI file.
Data is kept in the .MYD file.

Are you on Unix? Of so, then a mv (rename) of a file while the file is open does not impact the connection between MySQL or the OS and the file. mv only renames the file. Even rm, while the file is open, is does not fully take effect until the file is closed. You must get your head around those tricky things; they are part of the whole picture.

You have not said what Operating system you are using, nor were you specific on how you "deleted" the file, so I can't be more specific.
