JMP does lock data tables, if it can, when they are opened. That prevents two users from trying to commit edits to the table on top of each other. One of the users only gets read access. But that's only for data tables.

Some of these files are ‘active’ and may be appended to or even moved.<BR /><BR />I’m wondering whether JMP acts like Notepad where the file is not locked at all, or if there is a small chance the import will block another program manipulating the file.<BR /><BR />My question is for all versions of JMP 17 for Windows Fri, 06 Oct 2023 05:01:32 GMT https://community.jmp.com/t5/Discussions/Are-text-files-locked-when-importing/m-p/684420#M87018 bculver 2023-10-06T05:01:32Z https://community.jmp.com/t5/Discussions/Are-text-files-locked-when-importing/m-p/684495#M87023 I'm pretty certain JMP will not block another program when JMP reads a text file.
