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 everything looks unreadable, that does not mean the file is broken because many Parasolid transmit files are binary, so your next logical step is still to load it into a Parasolid-capable CAD program; for a safe technical glance, PowerShell can reveal early text lines or show hex bytes to help you understand the format, and if the file doesn’t appear in the CAD tool’s picker due to extension filtering, creating a renamed .x_t copy allows it to be selected without affecting the data itself.

XMT_TXTQUO is best understood as a Parasolid “transmit-text” geometry-exchange file, similar in role to the common .X_T format (and the binary .X_B / XMT_BIN variants), since many tools regard XMT_TXTQUO simply as another label for Parasolid’s text transmit, which is why it shows up with X_T under the MIME type `model/vnd.parasolid.transmit-text`, effectively marking it as a Parasolid text-model format.

The odd naming stems from some systems using compound extensions rather than `.x_t`, adopting formats like `XMT_TXT…` to denote “Parasolid transmit” and “text,” with suffixes like QUO serving only as variant identifiers in that environment; functionally, it’s still Parasolid text transmit geometry, and you can import it into any Parasolid-capable tool, using the workaround of renaming a copy to `.x_t` when your CAD program won’t list it automatically.

Opening an XMT_TXTQUO file usually involves treating it as a Parasolid text-transmit file and choosing any CAD tool that reads Parasolid, with programs such as SOLIDWORKS, Solid Edge, or NX letting you import it the same way as a normal .x_t—use File → Open/Import and either select Parasolid or show All files; since many tools filter by extension, the practical fix is duplicating the file, renaming the copy to .x_t, and importing that, which leaves the underlying geometry unchanged.

If you lack a full CAD program or just want to view or convert the model, a CAD translator/viewer tends to be the best shortcut: import the file and re-export as STEP (.stp/.step), which is broadly compatible across CAD platforms; when the file still won’t open, it’s commonly due to being a binary Parasolid type under a different name, being damaged or incomplete, or needing extra files, so asking the sender for a STEP export or verifying what tool created it is the safest next step.
