Scratch space is a disk at your disposition, that you can use to store whatever file you want. On scratch space, you can store any number of files of any dimension (compatibly with the overall disk space at disposition) you want. No check will be performed to the files contained in this server, and no backup of these files will be performed either.

• No check means that you can store any kind of files, of whatever dimension and nobody bother you about this.
• No backup means that no security system to recover your files will be performed. This in order to maintain low the level of work needs fo administration.
• The System Administrator does not lose time to check/verify/recover file stored in this disk space.

To access the scratch files all you have to do is connecting to the directory scratch in file server lthcserv7.epfl.ch by using Linux, Os X or Windows and you can use the disk space here for your needs. Recall that also others users need to use scratch space, so be gentle when you store your files. Currently the scratch space is around 400 Gbyte. A large amount of space just for crap files that one want to access but that aren't vital.
