Disappearing pakages

Hello, just a question to be sure that we don’t have a filesystem problem

if I upload a par file with


using proof, it is copied in /proof/workindirs/user/packages

but if I wait some seconds without any other commands the directory mypar and the file mypar.par disappear! Is it a feauture?

No, this is not a feature.
The files should stay there until you clean them with TProof::ClearCache() or TProof::ClearPackages().
