Esp name changed from upper case/capital letters to lower case/small letters - why?

Hi guys,

I have a very strange thing occurring with one of my mods respectivly save game. The mod JessiCompanion.esp was renamed to jessicompanion.esp and even after hours of searching I can't find a clue why or when this happened.
I use the original "Fallout Mod Manager - FOMM" and fiddled with some companion mods like "Unlimited Followers Everywhere" and "JIP Companions Command and Control", but only with test saves. I then continued with JIP Companions Command and Control for a few hours. It was by chance that I looked up my save games in FOMM and saw the difference.
The save with the changed jessicompanion.esp loaded fine and the game didn't showed any missing content message, so I don't know if it's a big problem.

I'm also not sure if I should continue playing that save (or if it's corrupt) and since it was only a few hours it's not a big deal.
I tried an older save together with JIP Companions Command and Control, saved it as a fresh one and Jessi stayed as JessiCompanion.esp. So I could just revert to this one.

But ... I just like to know how this could happened or what causes it? Any ideas?

Thanks in advance!

You have reason to be concerned.

 

The only reason for an ESP file to change the case of it's name is if it were renamed, such as when a new version of the file was created by editing it. Normal "play" of the game will not. "Save game files" have the name of your character or "autosave" and an extension of ".fos" (and if NVSE is installed, ".nvse" companion save files). The important thing is they do not use the name of any mods.

 

There is an option for "case sensitive file and folder names" in Win 10 on a folder by folder (directory) basis. It is "disabled" by default. If that option is enabled, you would have more than one file with the same filename, but different case in the names used as the system will consider them as two different files. It pre-dates the release of FNV, so the game will assume the filename case is "insensitive". FOMM will also assume "case insensitivity", so you will need to use the "Windows File Explorer" with "show extensions" enabled to check.

 

If you did not deliberately enable this option, I would suspect someone has been tampering with your computer. Do you share it with someone? If not or you connect to any unprotected network (such as open WiFi hotspots), strongly suspect malware until proven otherwise. Scan that file with multiple anti-virus products (such as "VirusTotal"), as your current one apparently has failed to detect this infection (if there is one).

Thanks for your answer, Dubious. I'm still on Win 7 (up to date but no meltdown/spectre patches for example, hardware too old), no unprotected network etc., just an old desktop pc for gaming.

Sadly I reinstalled the Mod via FOMM so I can't upload the "jessicompanion.esp" anymore. The original one (.fomod) and the saves are clean on VirusTotal. A Virus scan on my whole system didn't find any malware nor did Malwarebytes and the system runs fine for a long time now (as far as I can tell).

I had one malware alert (the only one on this system) with a file here on Nexusmods "NVAC - New Vegas Anti Crash" (the "NVME - New Vegas Memory Editor" file) a few weeks ago, but since there are so many reports of false positives in the thread and it landed in the quarantine I ignored it so far.

My thought was if it could be possible that anything like NVSE, Sortomatic, JIP Companions etc. could have renamed it out of (mod)conflict/bug, since JIP Companions has an .ini file for recognising the avatars like "Jessi=jessi". But thats probably just my desperate amateurish cross-thinking and if you say that's impossible ...

Maybe I should check in another forum specialised for infections.

Thanks anyway.
