What is the DCLS file format?
A file with the .DCLS extension is a file known as CATIA V4 Settings. It belongs to the Settings Files category. This format is associated with Dassault Systèmes S.A..
The reliable way to open a .DCLS file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
We are still gathering the list of programs that open .DCLS files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
