Precautions to observe when using PK7 disks with a computer
As occurs with the MS-DOS operating system, PK7 assigns file names not longer than 8 characters, plus an
identifying extension of three characters.
In the Macintosh, OS/2 and Windows 95 systems, a file name can be longer. When a name is modified on
these types of computers, the following rules should be observed:
• do not change the file extension because it identifies the file type and therefore, the relative structure.
• do not write names longer that 8 characters.
Furthermore, owing to some limitations of the MS-DOS and Atari systems (which other systems do not have),
it is essential to bear in mind the following advice:
• do not insert spaces within a file name (e.g.: «MY FILE»). MS-DOS is not able to recognize file names
containing spaces. To separate a name into two parts while retaining the MS-DOS compatibility, you must
proceed as follows:
separate two parts by the “underscore” symbol (e.g.: «MY_FILE»).
• do not assign two files the same name, one with uppercase letters and the other with lowercase (e.g.
«MYFILE» and «myfile»). MS-DOS and Atari make no distinctions between uppercase and lowercase
characters.
