What type of file is it?

However, you can look up the file type to be sure. Start by right-clicking the file icon and clicking “Properties” (“More Info” if you’re on a Mac). Then look for the file type under “Type of File” (“Kind” on a Mac).

Can I use a universal file viewer?

A universal file viewer is the way to go when you have OTM files that can’t be opened by any other program. Install a universal file viewer like File Magic (Download) and see if it will open your OTM file. Remember that if your file is not compatible, the universal file viewer will only open it in binary format.
