A TEXTEXPANDER file is a settings file created by TextExpander, a utility that allows users to save snippets of text such as addresses and phone numbers, and call them by typing shortcuts. It contains all of a user's snippets and can be used to manually transfer snippets from one device to another.

TextExpander enables you to save snippets of text that you repeatedly type, whether you are at home or the office, in order to save time. The snippets could be source code, directions, names, brand message, etc. You can then assign a shortcut to the snippet, which allows you to call and place a snippet through the typing of a shortcut. TextExpander saves the snippets in the cloud and updates across all of your synced devices. However, if you do not have sync setup or do not want to set it up, you can transfer the TEXTEXPANDER file by copying it and manually placing it on the other computer. The file's default location on a Mac is in the following location: [Home]/Library/Application Support/TextExpander/ You can also transfer the file to an iOS device from your Mac, PC, or iOS device. NOTE: The TEXTEXPANDER file was used by TextExpander until version 5 when it was replaced by the .TEXTEXPANDERSETTINGS file.
