Card index (Windows)
Card index ( English Cardfile , after the executable file cardfile.exe) is an additional program supplied with early versions of Windows that simulates a card index . Notes, contact information or similar short texts can be written, saved, searched and also printed on virtual index cards. Flashcards are saved in files with the file extension .CRD .
The card index was already included in the first version of Windows, Windows 1.0 , as a small demonstration program and remained part of the scope of delivery in all 16-bit Windows versions up to Windows 3.1 . The first versions of Windows NT up to and including Windows NT 3.51 contained a 32-bit version of the index that was backward compatible with .CRDfiles from Windows 3.1. Windows 98 and Me , but not Windows 95, included the 16-bit version on the Windows CD, but it was not installed by default and had to be manually copied to the hard drive if necessary.
Since Windows 3.0 the program automatically recognizes phone numbers in index cards and enables, if a modem is installed, the automatic dialing of the phone number at the push of a button. As of Windows 3.1, the index card supports OLE , so images can also be copied to an index card; the file format has been changed for this purpose and is incompatible with earlier versions of the card index. The Windows 3.1 format is publicly documented. A single tab can contain a 39-character title and up to 11 lines of 40 characters each. Since the index is limited to a single memory segment with a total of 64 KB, a maximum of 1260 index cards can be created per index.
More modern Windows versions no longer contain the card index, but there are numerous freeware alternatives. .CRD- Files could be imported into Schedule + via an optional plug-in and then exported from there in other formats if required.
