Sisulizer Files

Sisulizer uses several different file formats. Most of them are based on XML and can easily be viewed and edited using any XML or text file compatible editor. Because of XML they can easily be added to a version control database. All XML based Sisulizer files use UTF-8 encoding.

Sisulizer Project File

Sisulizer project file (.slp) is an XML based file that contains the localization project data. All translations and modification are kept in this file. If you want to backup your project, save this file. Project file contains all information about the project including original values, layouts, translations, images, etc. If you project contains lots of image and other binary data the project file might get very large. This will slow down opening of the project file. In such case you can exclude binary resources and binary data type.

Sisulizer Desktop File

Sisulizer desktop file (.sds) is an XML based file that contains the desktop settings of the Sisulizer project. If this does not exist Sisulizer will create a new and will use the default settings.

Sisulizer Item File

Sisulizer item file (.sli) is an XML based file that contains exported Sisulizer items such as fonts, component mappings and file mappings.

Sisulizer Language File

Sisulizer language file (.sll) is an XML based file that contains exported Sisulizer languages.

Sisulizer User Dictionary File

Sisulizer user dictionary file (.sld) is a text file that contains custom spell checking dictionary.

Sisulizer Translation Memory File

Sisulizer translation memory file (.stm) is an XML based file that contains back-up data of the internal translation memory.

Sisulizer Package File

Sisulizer project file (.sle) is a compressed file that contains the exchange project file and other possible file(s) needed by the translator. It uses the same file format as ZIP files.

Sisulizer Options File

Sisulizer options file (Sisulizer.slo) is an XML based file that contains the settings of your Sisulizer. It is located on the Sisulizer installation directory (Windows XP) or Sisulizer data directory (Vista).

Backup Files

Any file having ~ character in the beginning of the extension (e.g. sample.~slp) is a backup file. It contains the pervious valid file. You can reverse you version by deleting the new file and renaming the backup file by removing ~ character.
