What is a BKC file?
A .BKC file is most commonly a Backup4all Backup Catalog created by software from Softland. This file acts as an index for your backups. It stores technical metadata about file versions, folder structures, and backup rules, while the actual data is often stored in separate archives.
The .BKC extension is also used by other software. It can be a book collection database backup created by Book Collector. It can also be a data acquisition project file for BK Connect, which is specialized engineering software made by Brüel & Kjær.
How to open BKC files?
To open and use a .BKC file, you usually need the original software that created it. If the file is a backup catalog, you must open it in Backup4all to restore your files. If it is a book collection backup, you must import it into Book Collector.
Because .BKC has multiple possible meanings, you might not know which software you need. Opening the wrong file in the wrong software will cause errors. You should avoid modifying the file in a simple text editor, as this can corrupt the backup index.
