A quick sanity check for an XMT_TXTQUO file is a protective initial step that it’s probably a Parasolid transmit CAD file, beginning with context clues from engineering or CAD-related senders, then reviewing Windows Properties for size indicators, and if desired, opening it in a plain text viewer to look for structured text associated with transmit forms, being careful not to save or let any program modify the file.

If it looks like unreadable gibberish, that doesn’t necessarily signal a problem—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 looks "weird" because some software pipelines don’t stick to the usual `.

Opening an XMT_TXTQUO file generally means working with it as a Parasolid text-transmit file and importing it using Parasolid-compatible CAD software—SOLIDWORKS, Solid Edge, or Siemens NX—via File → Open/Import and either choosing Parasolid or switching to All files so it loads like a standard .x_t; when the extension is filtered out, the simple workaround is to make a copy, rename that copy to .x_t, and import it unchanged.

If you don’t have full CAD tools or only need basic viewing or conversion, using a CAD translator/viewer is often the cleanest approach: load the file there and export to STEP (.stp/.step), a format accepted by nearly all CAD applications; if the file still fails to open, it’s likely a binary Parasolid variant, a corrupted or partial file, or something that requires companion data, so requesting a STEP version or confirming the source software is the most reliable fix.
