What are BTC files and how to open them

Are you having problems opening a BTC file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your BTC files.

What is a BTC file?

A .BTC file is a BeckerTools Compressed Archive/backup file.

BeckerTools Compressed Archive/backup files store archived and compressed data produced by the BeckerTools suite, a collection of file-and-disk utilities created for MS-DOS and Windows 3.x by Abacus (Data Becker). These files are used to bundle one or more files (or entire directories) into a single archive while reducing disk space through compression.

The backup utility in BeckerTools writes these archives when a user runs a compression or backup task, grouping files together and applying a compression algorithm so that the resulting archive is smaller than the sum of its parts. Later, BeckerTools restores or extracts files from the archive back into their original form.

Internally, files of this type begin with a signature at the start of the file that identifies them unambiguously. The first bytes read are an ASCII string: "BeckerTools BTCFile(DataBecker)" located at offset zero. This serves as a header to confirm the file is a BeckerTools compressed archive.
