impossible to save

hi, i have caelinux on a virtual machine...and i cant save file in salome, it tell me that i don't have permission.
Can anyone help me?

Hi,

If you are new to linux, try to open a terminal window and list the permissions of the sub-directory you are trying to save to. Optionally, use a file manager like nautilus if you prefer the GUI (Graphical User Interface) method of using a PC. A little more detail about your problem (OS, version, etc.) where you are trying to save to, etc. would help us guide you better.
