LLX File – What is .llx file and how to open it?
LLX File Extension
LabVIEW VI Library Backup File – file format by National Instruments
A backup file created by LabVIEW, a graphical programming environment; stores a backup of a LabVIEW VI library file (.LLB); used to recover the library if the original file is corrupted or lost.
File Format
LLX files are backup files created by National Instruments’ LabVIEW software, a graphical programming environment used for data acquisition, signal processing, and other engineering tasks. These files store a compressed version of a LabVIEW VI (virtual instrument) file, which contains the source code, data, and other information for a specific LabVIEW program. LLX files are typically created automatically as backups when saving VI files, ensuring that a recoverable copy of the program is available in case of data loss or corruption.
Usage
LLX files can be useful for recovering lost or damaged LabVIEW programs, as they can be restored using the LabVIEW software. To restore an LLX file, users can simply navigate to the file in the LabVIEW application and select the ‘Restore’ option. The program will then be restored to its original state, allowing users to continue working on it as if it had not been lost. Additionally, LLX files can be used to create standalone executable files for LabVIEW programs, allowing them to be run on computers without the LabVIEW software installed. This can be useful for distributing LabVIEW programs to users who may not have the necessary software.
Opening LLX Files Using LabVIEW Software
LLX files are backup files for LabVIEW virtual instrument (VI) libraries. These files can be opened and restored using the LabVIEW software, a graphical programming environment developed by National Instruments. To open an LLX file in LabVIEW, follow these steps:
- Launch LabVIEW and create a new VI library.
- Right-click on the library name in the Project Explorer window and select “Restore from Backup”.
- Navigate to the location of the LLX file, select it, and click “Open”.
LabVIEW will restore the backup file and add the VIs back into the library. Note that the original VIs that were backed up must still be present in the same location where they were saved when the backup was created.
Alternative Methods for Opening LLX Files
While LabVIEW is the primary method for opening LLX files, there are a few other potential ways to extract data from an LLX file if LabVIEW is not available:
- Text Editor: LLX files are essentially text files containing a list of VI references and additional metadata. A text editor like Notepad or Notepad++ can be used to view and extract this information.
- Third-Party Tools: Some third-party tools, such as LabVIEW File Extractor, can be used to extract VIs from LLX files. These tools typically work by extracting the VI references and metadata and then rebuilding the VIs from scratch.
- LabVIEW Command Line: It is possible to open an LLX file using the LabVIEW command line interface (CLI). However, this method requires specialized knowledge and is not recommended for general users.
LabVIEW VI Library Backup File (.LLX)
A LabVIEW VI Library Backup File (.LLX) is a file format used by National Instruments’ LabVIEW software. It is a backup file that stores copies of VI (Virtual Instrument) libraries, which are collections of VIs and other LabVIEW objects. The .LLX file format is used to preserve the VI libraries in case the original files are accidentally deleted or corrupted.
The .LLX file format contains a binary representation of the VI libraries, including the VIs, subVIs, and other objects. This allows the VI libraries to be restored to their original state in the event of a file loss or corruption. .LLX files are typically created automatically by LabVIEW when a VI library is saved or backed up. They can also be created manually using the “Save As” command in LabVIEW.
