A quick sanity check for an XMT_TXTQUO file is a simple test that it’s probably a Parasolid transmit CAD format, with the first clue being where it came from—engineering workflows or CAD-related senders usually imply 3D geometry—followed by checking the file’s Properties for size hints, and finally doing a non-destructive peek in a text editor to see if structured text appears, making sure not to save or allow reformatting.

If it appears as unreadable characters, that doesn’t imply corruption—it may simply be binary data meant for a Parasolid importer, and the next step is still to load it into a CAD tool that supports Parasolid; if you want a safe technical peek, PowerShell can show the first lines or hex bytes so you can see whether it’s text or binary, and when a CAD program filters out the file by extension, a useful workaround is making a copy, renaming it to .x_t, and importing that version without changing the underlying data.

XMT_TXTQUO functions as a Parasolid "transmit-text" exchange file, meaning it’s a way to package 3D CAD geometry for transfer between tools that read Parasolid data; in practice it belongs to the same family as .X_T (and the binary .X_B / XMT_BIN), with many systems treating XMT_TXTQUO as just another label for Parasolid’s text-transmit format, which is why it appears alongside X_T under the MIME type `model/vnd.parasolid.transmit-text`, essentially indicating a Parasolid text model.

The name looks "weird" because some software pipelines don’t stick to the usual `.

Opening an XMT_TXTQUO file simply involves treating it like a Parasolid transmit-text CAD file and using a program that reads Parasolid geometry—SOLIDWORKS, Solid Edge, NX—by going to File → Open/Import, selecting Parasolid or showing All files, and letting the software translate the B-Rep; if the program won’t show it due to the extension, copying and renaming the file to .x_t lets the importer accept it without altering the underlying model.

If you don’t have a full CAD suite or only need viewing or conversion, a CAD translator/viewer is usually the easiest option: import the file and export it as STEP (.stp/.step), which nearly all CAD systems accept and is ideal when sending geometry to someone not using Parasolid-based tools; if nothing opens the file, it’s usually because it’s actually a binary Parasolid variant, it’s incomplete or corrupted, or it relies on companion files, so the safe move is to ask the sender for a STEP export or confirm the originating software before retrying with correct settings.
