@arnaud-derette , I have never used that plugin. But when I went to their homepage (https://github.com/Pascal-Krenckel/NppGZipFileViewer), they say, “This plugin is deprecated, please switch to CompressedFileViewer.” Once an author deprecates a plugin, there won’t be support for requests. I have put in a request to ask that the author remove the deprecated plugin from the Plugins Admin list (and, if they want, to add the replacement plugin into the list). But you should try their replacement plugin. And if it doesn’t improve your experience, you can go to the CompressedFileViewer’s issue tracker (https://github.com/Pascal-Krenckel/CompressedFileViewer/issues), and make your request(s) there.

@RWieber79 , I had been hoping the plugin’s author, @pnedev, would have responded by now. I might suggest trying without the XMLTools plugin, to see if it’s a strange plugin interaction. Or if you could give some clues as to whether there’s something unique about these XML: are they very similar files, with only a few lines different? Or are they highly different, with only a few lines of similarities? Big files, or small? Which ComparePlus options are enabled (do a screenshot showinng the entire ComparePlus sub-menu, so we can see all the checkmarks). (ComparePlus has never crashed on me, so I’m just giving some generic debugging suggestions. If anyone else has ideas, feel free to chime in.)

@baberzaman you might want to check out Kereds or my LSP client for Notepad++.

Hi, All, I did additional tests, especially regarding characters allowed with or without quotes ! Although practically any character can be put within a file name when using the rename option of the Explorer, it happens that, under DOS, it is safer to surround the filename with double quotes when you insert most of the allowed symboles So, here is an updated version of my information part : Syntaxes / Chars ALWAYS forbidden : \x00-\x1F " * / : < > ? \ | \x7F : . at the END of file name : SPACE at the END of file name : ALL DOTS file name : PRN AUX NUL : COM1 COM2 com3 COM4 COM5 COM6 COM7 COM8 COM9 COM¹ COM² COM³ : com1 com2 com3 com4 com5 com6 com7 com8 com9 com¹ com² com³ : LPT1 LPT2 LPT3 LPT4 LPT5 lpt6 LPT7 LPT8 LPT9 LPT¹ LPT² LPT³ : lpt1 lpt2 lpt3 lpt4 lpt5 lpt6 lpt7 lpt8 lpt9 lpt¹ lpt² lpt³ Chars allowed WITHIN double quotes : ! % & ' ( ) + , ; = [ ] ^ ` { } ~ : SPACE when at BEGINNING of file name Chars allowed WITHOUT double quotes : # $ - @ _ : . if NOT at END of file name : SPACE if NOT at BEGINNING or END of file name You’ll note that my regex, described in my previous post, allows most of the symbols, even without quotes, as they, generally, can be inserted when using the Explorer !
