Hi @Madhubalan-p,

Since the file system structure has changed with Zowe Explorer v3 for PDS members, you'll need to update your file associations to handle the new format. See this article from Zowe Docs for more info: https://docs.zowe.org/stable/user-guide/ze-usage-tips/#configure-the-detected-language-of-a-file-or-data-set

Here's a RegEx expression that you can use to quickly find/replace those associations with the new format:

Find: \*\.(.+?)\*
Replace: **/*$1*{,/*}
