Duplication of M-files in my matlab directory

Sometimes, my m-files get duplicated in the directory after writing, saving and execution. The duplicated copy , however, has all the command buttons disabled and cannot run. Please, who has experienced this and what is the way out? I fear to delete them as I do not know what could be the impact

[Geoff Hayes]

Do the files have the same name or is there a tilde (~) appended to the end of the file name (after the extension)? Or is the file extension asv (rather than m)?

See what is an asv file for details.

The copy usually has an asv extension

[Geoff Hayes]

Those files can (probably!) be deleted. Check the link I included in my previous comment.

Great comment!

It is probably the auto-save-files you see (as indicated by Geoff Hayes). There is an Autosave entry in the preferences menu.
