A quick sanity check for an XMT_TXTQUO file acts as a harmless pre-check to see if it’s likely a Parasolid exchange file, beginning with its origin—CAD-heavy sources such as project folders, shops, or designers strongly suggest 3D geometry—while Windows Properties may not identify it but can still provide file-size clues, and a careful look in a text editor may show readable structured text typical of transmit variants, as long as you avoid altering or saving the file.

If it looks like unreadable gibberish, that isn’t proof anything is wrong—it often just means the file is binary or packed, and the correct next step is still to try importing it into a Parasolid-capable CAD tool or translator; for a slightly more technical but safe inspection, you can use PowerShell to show the first text lines or dump a few bytes in hex to distinguish text from binary, and if a CAD program hides the file in its Open dialog due to extension filters, you can duplicate the file and rename the copy to .x_t so the software will accept it without altering its contents.

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 name appears "odd" because certain ecosystems avoid the standard `.x_t` and adopt multi-part extensions like `XMT_TXT…` to indicate "Parasolid transmit" and "text," with the trailing piece (for example QUO) simply serving as an internal variant marker, and what actually matters is that the file remains Parasolid text transmit geometry, so you should open it in a Parasolid-reading CAD program, or if it’s filtered out, make a duplicate and rename that copy to `.

Opening an XMT_TXTQUO file usually involves recognizing 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 is often the most practical route: 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.
