What is blk file? How to open blk files?
File type specification:
Tape format used by Sinclair; identical to Z80's .TAP files.
The TAP- (and BLK-) format is nearly a direct copy of the data that is stored in real tapes, as it is 'written' by the ROM save routine of the ZX-Spectrum. It is supported by many Spectrum emulators.
This blk file type entry was marked as obsolete and no longer supported file format.
This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
