When trying to open an ALG, the error message “Try again,unable to lock file” appears. In addition, a file by the same name as the ALG file exists in the same folder but with a NLF extension and zero KB file size. Once the NLF file is renamed to a different extension or deleted, the ALG opens but the edits were not saved.
The NLF file is created when multiple users are accessing the same ALG and one user needs to save changes to that file. This temporary file is automatically deleted once changes have been written to the ALG file.
