Extract text from backup files (BK1)
To convert BK1 backups to another format, you need Autodesk ReCap or other Backup software.
To convert other file formats to the "Software Backup File" file type, you need software like Autodesk ReCap or a similar tool.
A .BK1 file is a generic backup extension utilized by several disparate software applications to prevent data loss. The most prominent user of this format is Autodesk ReCap, a 3D scanning and point cloud processing software. In ReCap, a .BK1 file is essentially a standard ZIP archive that contains a backup of the main RCP project. Other notable applications using .BK1 include Moneysoft Payroll Manager for preserving financial databases, IBM SPSS Amos for structural equation models (stored as UTF-16 (LE) text), and ERwin Data Modeler for database schemas. Some legacy AutoCAD systems also generate .BK1 files alongside standard BAK files.
The primary disadvantage of a .BK1 file is its extreme fragmentation. Because "BK1" simply stands for "Backup 1", the internal structure is entirely dependent on the software that created it. You cannot open a Payroll Manager .BK1 file in Autodesk ReCap. Furthermore, these files are proprietary, often useless without an active subscription to the expensive host software, and are completely unsupported by web browsers or standard document viewers.
Converting a .BK1 file is usually a matter of restoring it within its native environment. If you have an Autodesk ReCap .BK1, the best conversion target is a standard ZIP archive, which you can simply rename and extract to retrieve your RCP files. For SPSS Amos, you need to restore it to an AMW file. General-purpose online converters fail with .BK1 files because they lack the context of which software generated the backup. This makes .BK1 files notoriously difficult to open or convert blindly. If our analysis detects an underlying ZIP archive or UTF-16 text structure, viewing or extracting the contents may still be entirely possible.
Convert.Guru analyzes your BK1 file, detects the exact format, and lets you read the text inside.
Users also converted RCP and BK2 files.
If you want to convert BK1 file to BAK, BACKUP, OLD, TMP, TEMP, ARC, ZIP, TAR, GZ, 7Z, RAR or ISO, you can use Autodesk ReCap or similar software from the "Data Recovery and Archiving" category. In the File menu, look for Save As… or Export….
To convert SNAPSHOT, OLD, IMG, RESTORE, ISO, COPY, VMDK, TMP, VHD, BAK, ARCHIVE or BACKUP files to BK1, try Autodesk ReCap or another comparable tool in the "Data Recovery and Archiving" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our BK1 converter.
