microsoft windows Users who want to create a bat file usually start by creating a text document in Windows and change the file extension afterwards to bat. The same principle is used when creating other formats like html documents. The following tip is not limited to Windows Explorer or text documents. It works as well in web browsers like Internet Explorer or Firefox, email clients like Mozilla Thunderbird and Microsoft Outlook and practically any program that is offering to save files.

The save as file dialog is usually offering a few file formats a document can be saved in. This limitation can be overridden by putting the name and file extension in quotation marks.

It is therefor possible to save information in different data formats even if they are not supported by the software program. It is even possible to select data formats that are not compatible at all with the data. A text document could be saved as an excel document or zip file. This will obviously throw an error when trying to open the file unless the right viewer is selected.

    Very nice trick. Most software is sane enough to allow save file under any name, but some (especially parts of Windows) are extremely stubborn about that.

    Similar good trick for opening any file when there is no “All files” option is typing *.* for file name and clicking Open. Will override filter and show all files in folder.
