How to open file with .BACKUP extension?

Don’t you know what program to use to convert the .BACKUP file? Do you want to convert a .BACKUP file into a different format? Below you will find helpful information.

File extension .BACKUP

Full Name Developer Category
Backup Of Current ISAPI Application N/A Backup Files
.BACKUP

The BACKUP file extension is a backup file format used by various software applications, including Microsoft Word, Adobe Acrobat, and Microsoft ISAPI. This file type can be used to preserve user data or to store files that have been altered from their original versions. A BACKUP file is generally generated with the intention of carrying out a backup or restore procedure on an existing application. It may contain critical user data and settings, such as preferences and history.

Data Format and Structure

The BACKUP file format generally consists of a base 64 encoded block of binary data that is compressed using either zip archive or RAR Archive. The compressed data is then further protected by a checksum algorithm. Additionally, some BACKUP files may also be encrypted, to further protect the data contained within them. The structure of BACKUP files can vary greatly between different software applications; however, generally the content does remain mostly intact between different operating systems.

Similar File Extensions

Some other file extensions used for backing up application data include: .BAK, .BCK, .QIC, .TBK, and ZIPC.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .BACKUP) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .BACKUP extension.

When choosing the software we can select the system to use this software every time.

Remember!
Using it for the first time it is good to check whether the .BACKUP file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .BACKUP extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .BACKUP extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .BACKUP file. Sometimes you have to repeat the operation several times.

Other instructions

If none of the programs listed by us to work with the .BACKUP file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.

In the vast majority of cases you will find the program dedicated to support the .BACKUP file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .BACKUP file) will be extended to the maximum.

It is also good to check

  • if the .BACKUP file has no errors
  • or if it has been copied (or downloaded by the browser) thoroughly
In such a case it is best to try to download the .BACKUP file again from the same source on the Internet (or look for another source). If you received the file from another person, ask this person to re-send it. However, if the file was copied from some media, repeat the copying operation.
