An SPL file is a file created by Windows when a user submits a print job. It contains the spooled print data, which includes the digital document contents sent to the printer for printing. SPL files save data in a raw printer format and are used as a temporary data store for the print job, which is emptied when the job completes.

SPL files are saved to the following directory when a print job is submitted: C:\Windows\System32\spool\PRINTERS\.

NOTE: Windows also saves an .SHD file to the same directory as the SPL file when printing. This "shadow" file allows the print job to be resubmitted if it is interrupted.

You can open an SPL file and view its contents in EMF Printer Spool File Viewer (Windows) and SPLViewer (Windows). You can also use these applications to print the print job described in your SPL file.

An SPL file is a schematic diagram created by sPlan, a schematic editor for Windows. It contains a schematic circuit diagram, which consists of circuit components such as fuses, diodes, resistors, switches, contacts, transistors, relays, connectors, hydraulics, and capacitors.

An SPL file is a Splunk application package used by Splunk Enterprise, a program used to search, analyze, and visualize business data. It stores all the files that make up the application, which may include scripted and modular inputs, reports, custom UI dashboards, event types, field extractions, and workflows. SPL files are used to upload apps to Splunkbase, which is the Splunk app store, to distribute them to other Splunk users.

You can open SPL files using Splunk Enterprise or Splunk Cloud, which is the web version of Splunk Enterprise. Some examples of Splunk apps include User Role Checker, PyDen Manager, Slack Notification Alert, Cisco Network App for Splunk, and Palo Alto Networks App for Splunk.

SPL files are the same as .TAR.GZ files but use the .spl file extension instead of the .tar.gz extension. They store the application files in TAR archives (tarballs), which are compressed with the standard GNU zip (gzip) compression algorithm.

You can package your Splunk app as an SPL package by opening a command prompt and navigating to the following directory:

$SPLUNK_HOME/​bin/​

Then, enter one of the following commands depending on the computer you are using:

• Windows - splunk package app your_app_name
• macOS - ./splunk package app your_app_name

An SPL file is a spelling dictionary used by Vim, a popular Linux text editor. It contains a language-specific dictionary used to provide spell check functionality in Vim. SPL files are stored in Vim's ~/​vim/​runtime/​spell directory.

Like many text editors, Vim (and its variants) contains spell check functionality that highlights users' spelling mistakes. To turn on spell check, Vim users must either enter the command setlocal spell in Vim's command line or add the set spell command to their .VIMRC file.

By default, Vim uses English spelling dictionary files, named en.characterset.spl, to check users' spelling. However, users can modify their VIMRC file's set spelllang setting to use other languages' spelling dictionaries. Vim contains over 100 SPL dictionaries, grouped into over 50 languages. In addition to these SPL files, Vim uses SUG and DIFF files to highlight misspelled words and show spelling suggestions.

Vim SPL files are not meant to be opened. If you want to use an SPL file as your Vim spelling dictionary, you can do so by:

1. Opening your Vim VIMRC file.
2. Updating the set spelllang setting to use your SPL file's language code. For example, if your SPL file is named fr.latin1.spl, update the setspelllang setting to read set spellang=fr

If necessary, you can download SPL files (as well as each language's SUG and DIFF files) from ftp.vim.org.
