Conversion of bak files to doc file format

It is possible to convert .bak files to MS Word documents (.doc, .docx) only if these backups actually contain some kind of document in first place. Usually  programs just make a copy of certain file and change the extension from the original to bak, in this case from doc to bak, in order to prevent overwrite of the original data. Just try to rename the suffix and see if that works, if not you will most likely have to recover the file using the original software for that particular .bak file.
