| - | * //Enough// space on ''C:\''. Microsoft instructions say //The Windows Subsystem for Linux only runs on your system drive (usually this is your C: drive)// | + | === Some important disk locations === |
| - | * Exporting a //simple// Ubuntu configuration (after doing everything from //Base installation// to //Advanced configuration// below) with the [[other:win10wsl#creating_a_backup_of_the_linux_running_in_wsl|wsl --export]] command generated a 2.7 Gb tar file (uncompressed), so it's probably good to **start with at least 3 Gb of free space on ''C:\''** (and you always need to keep enough free space on ''C:\'' for regular Windows operation) | + | |
| - | * The Linux ''/'' and ''/home'' partitions will always be on ''C:'', but the data files can be on any Windows disk/partition (or external drive) of the computer | + | * Accessing **Windows files from Linux**: ''/mnt/''\\ e.g ''C:\'' is available in ''/mnt/c'' |
| - | * the Windows partitions will be available and accessible in ''/mnt/'', so you can store data on other partitions (e.g. the content of the Windows ''D:\'' partition will be available in ''/mnt/d'' in Linux) | + | |
| - | * The files will be installed in **hidden partitions of the current user's directory on ''C:\''**: e.g. ''C:\Users\<your_login>''. Other users of the same Windows 10 computer would have to install Ubuntu again, in their own user directory | + | * Accessing **Linux files from the Windows Explorer**: ''\\wsl$'' |
| - | * Checking the properties of ''C:\Users\<your_login>'' will **not** report an accurate size and number of files, because lots of files and directories are hidden! On the test laptop, the reported size of the user backed up directory (with [[other:win10apps#syncbackfree|SyncBackFree]]) was ~20 Gb (user data, WSL+Ubuntu, custom install of the CDAT 8.1 python distribution) | + | |
