QR-Tekst
QR-Tekst is a word processor developed by the Polish company Malkom, for the Polish market. It was originally released for DOS. A Windows version 1.0 followed in 1993. The final release, version 2.0 for Windows, came out in 1995.
Back in its day, QR-Tekst was widely used in various Polish government institutions, including the Parliament.
In addition to its native format, QR-Tekst 2.0 can also save and open documents in other popular formats of its day, including the native format of Cyfroset, a Polish desktop publishing program.

Native document format
QR-Tekst's native file format uses the .qrt extension. (QR-Tekst 5.0 for DOS, and probably older versions too, does not give any extension to the files it saves.[1]) The format varies between versions of the program; QR-Tekst for Windows 2.0 offers three different save options, corresponding to:
- QR-Tekst 5.1 (DOS),
- QR-Tekst for Windows 1.0,
- QR-Tekst for Windows 2.0.
Identification
.qrt files, saved with QR-Tekst for Windows v2.0, begin with the following bytes:
- format: QR-Tekst 5.1 (DOS):
-
11 4D 41 4C 4B 4F 4D 0D 0A 71 72 74 35 30 0D 0A - Bytes 2-16 spell out:
MALKOM qrt50<CR><LF>
-
- format: QR-Tekst for Windows 1.0:
-
11 4D 41 4C 4B 4F 4D 0D 0A 71 72 74 36 30 0D 0A - Bytes 2-16 spell out:
MALKOM qrt60<CR><LF>
-
- format: QR-Tekst for Windows 2.0:
-
11 4D 41 4C 4B 4F 4D 0D 0A 71 72 74 36 31 0D 0A - Bytes 2-16 spell out:
MALKOM qrt61<CR><LF>
-
The next part of the file is the file description metadata (if any was entered when saving), stored in ASCII format. It is followed by two bytes, 0D 0A, i.e. <CR><LF>.
After this come some settings and formatting information. The actual content of the document is stored later in the file, in plain text, but interspersed with control codes.
Other associated formats
A fresh installation of QR-Tekst 2.0 includes files with several other unique types:
- Template files (.std): Pre-made document templates. Their structure appears to be very similar to .qrt files.
- Dictionary files: Used by the built-in spellchecker. QR-Tekst for Windows 2.0 includes the files SLOWNIK1.POL, SLOWNIK.GER, and SLOWNIK1.ENG, corresponding to Polish, German, and English dictionaries, respectively. There are also several extra *.pol files containing grammatical suffixes, probably to help the spellchecker to recognize inflected forms of Polish words. The package also includes a file SYNONIMY.POL, which is used by the program's thesaurus function.
- Conversion instructions (.cnv): Files which instruct QR-Tekst how to convert between various text formats and encodings. They use a simple, human-readable format.
