# How to check if hardlinks are working
|
|
|
|
You've followed the guide step by step but still want to check if hardlinks are working, or someone on the Sonarr/Radarr support team asked you to check if your files are hardlinked.
|
|
|
|
You can use 3 options to check if you got working hardlinks.
|
|
|
|
_All methods require you to log in to your terminal with PuTTY or similar software._
|
|
|
|
!!! warning
|
|
|
|
- You **CAN'T** create hardlinks for directories :bangbang:
|
|
- You **CAN'T** hardlink across separate file systems, partitions, or mounts :bangbang:
|
|
- Some file systems, such as exFAT, are known not to support hardlinks and should be avoided (double-check if you are unsure!)

## Usenet
|
|
|
|
!!! info "If you are using Usenet, these examples won't work due to making use of instant/atomic moves and not hardlinks.<br><br>Still want to test if it works?<br><br>Test an import of a 4k remux, or any other big file, and you should notice it's almost instant and not a slower and more I/O intensive copy + delete."
|
|
|
|
## Method 1: Using ls
|
|
|
|
This is the easiest to check in our opinion.
|
|
|
|
In your terminal `cd` to your download location and run `ls -al` or type `ls -al /path/to/your/download/location/`
|
|
|
|
You will get a listing of all your files and on the left side you will see a couple of numbers, every file with a number above 1 are hardlinks.
|
|
|
|
|
|
|
|
- Red rectangle - Not Hardlinked
|
|
- Green rectangle - Hardlinks
|
|
- Blue rectangle - Folders/Directories you will need to go into them to check if the files are hardlinked.
|
|

## Method 2: Using stat
|
|
|
|
This way requires a bit more work.
|
|
|
|
- In the terminal type: `stat /path/to/your/download/location/file.mkv`
|
|
- In the terminal type: `stat /path/to/your/media/location/file.mkv`
|
|
|
|
You will get 2 results you can use to compare several things.
|
|
|
|
|
|
|
|
1. Links: Everything above 1 means it's hardlinked
|
|
1. Inode: if the numbers match, you know the files are hardlinked
|
|
|

|

|
|
## Method 3: Using Inode copies
|
|
|
|
- In your terminal `cd` to your download location and run `ls -i file.mkv` or type `ls -i /path/to/your/download/location/file.mkv`
|
|
|
|
This will reveal the inode of your file on the left side of the file.
|
|
|
|
|
|
|
|
- In your terminal type: `find /mnt/user/data/ -inum ###` or `find . -inum ###` if you're in your root folder.
|
|
|
|
!!! note ""
|
|
|
|
`###` = Your inode number on the left of the file you found.
|
|
|
|
|
|
|
|
It will list all files linked with the same inode number.
