A WFT file just means the file ends with `.wft`, but because `.wft` lacks a universal meaning, its purpose changes based on origin, commonly appearing as a GTA IV model file found with a `.wtd` texture, an Oracle Workflow Builder data/definition file, or an interferometry wavefront dataset for mirror or optical analysis.

The quickest way to figure out which type of WFT file you have is to check the folder it originated from and what files sit next to it, since a GTA mod or game folder points to the GTA version, Oracle/EBS export folders point to the Oracle workflow type, and optics/testing directories point to wavefront data, after which you can do a simple text-versus-binary check by opening a copy in Notepad to see whether it shows readable text or mostly unreadable symbols, and if you need stronger confirmation you can inspect the first bytes or run PowerShell commands like `Format-Hex` or a strings-style scan to look for clues such as vehicle names, Oracle workflow terms, or optics keywords, then load the file with the right toolchain—GTA mod tools, Oracle Workflow Builder, or optics software.

When I ask which app or project produced the WFT file, it’s because `.wft` doesn’t correspond to a single standard, and knowing the source usually identifies it instantly: files found in GTA IV mod packs or vehicle-asset folders are almost certainly GTA model files used with OpenIV, those from Oracle/EBS workflow setups are Oracle Workflow definition/data files, and those from optics or interferometry work are wavefront datasets, meaning the best clue is the folder or download context and the neighboring files rather than the extension alone.

In real-world usage, a “.wft” file almost always refers to one of several known formats, and determining the right one depends on its system context: in GTA IV modding circles it’s the familiar vehicle-model file used with `.wtd` textures and opened in OpenIV, in enterprise workflows it’s an Oracle Workflow Builder data file used for defining and migrating workflow structures, and in optics/interferometry work it’s a DFTFringe wavefront data file associated with measurement and correction tasks rather than gaming or ERP automation.

To identify what kind of `.wft` file you have, the best strategy is to look at where it was obtained, note nearby files, and peek inside briefly, because many ecosystems reuse the `.wft` extension; if it’s from a GTA IV mod bundle or a modding directory and includes a matching `.wtd` texture or vehicle-related files, it’s likely the GTA model type used with OpenIV, whereas a file from an Oracle workflow environment indicates an Oracle Workflow Builder definition/data file.

If the file shows up in optics or interferometry contexts—mirror-testing workflows, wavefront correction tasks, or DFTFringe operations—it might be a wavefront data file, and aside from contextual clues you can inspect a copy in Notepad to judge whether it reads like text or resembles binary gibberish, and for a decisive identification you can view its header bytes with PowerShell’s `Format-Hex` or gather readable strings to spot telltale patterns such as GTA asset terms, Oracle workflow vocabulary, or optics/wavefront keywords that quickly clarify which type of `.wft` it is.
