High capacity and fast fill of AppData\Local\Temp\jnjl32fl folder

Hi,

Is it safe to delete the Temp folder in C:/Windows/Temp?

Yes, all *files* in the temp folder (not the folder itself) can, and should be, deleted periodically.

The temp folder provides workspace for programs. Programs can create temporary files there for their own temporary use. Each program should delete all its temporary files when it closes, but for various reasons it doesn't always happen (for example,
if the program crashes, it never gets to do this). That's why it's a good idea to periodically clean out anything left there.

Also note that there are some program installations which work in two steps. The first step concludes by writing temporary files and rebooting. The second step starts automatically after rebooting and needs to find those files there (and then deletes
them when it's done).

Other than doing it automatically when rebooting (that would interfere with installations like the kind I described), it's always safe to delete the contents of the temp folder. Because it's safe to delete any temp files that aren't open and in use
by an application, and since Windows won't let you delete open files, it's safe to (try to) delete them at any time. If any fail to delete because they're open, they'll either be deleted automatically when the app using them closes, or you'll get them the
next time you delete manually.

Some people may suggest that you reboot before deleting anything, but that's not necessary, for the reason described above (on the other hand, it doesn't hurt to do it).

 

AppData/Local/Temp folder has deleted a file

Stupidly I have been working on a temporary CAD file in AppData/Local/Temp folder, not sure how it happened (power cut maybe) but it came up as the top file on my list of recent files and I just opened it worked on it a few days ago and saved it. Actually
I must have done this several days in a row. Scroll forward to today and it still comes up on my file list but doesn't seem to actually exist anymore. I have tried a file search with no luck. Several days work lost it seems. Does this file still exist somewhere?
Any ideas?

Thanks

Will
