### What are Hardlinks
|
|
|
|
|
|
??? question "**What are hardlinks?** - [Click to show/hide]"
|
|
|
|
|
|
- [**Short answer**] Having a file in multiple locations without using double your storage space.
|
|
|
- [**Long answer**] Hard links are a way for a copy operation to be instant and not consume space for those additional copies.
|
|
|
|
|
|
Every file is a hard link: some metadata that points at blocks on the file system, **which is why they're restricted to the same file system**. There can be as many metadata files pointing at those blocks as needed and the blocks know how many links point to them. Once the blocks have 0 links, they're considered deleted.
|
|
|
|
|
|
This means:
|
|
|
|
|
|
- You can delete any "copy" w/o impacting the others.
|
|
|
|
|
|
Your download client can remove it's "copy" w/o impacting the library "copy". The library "copy" can be removed by Plex or Sonarr/Radarr or yourself w/o impacting the download client "copy".
|
|
|
|
|
|
- Space is only regained when all "copies" are deleted.
|
|
|
|
|
|
- Modifying the file will impact all "copies".
|
|
|
|
|
|
For example, modifying the id3 tags of a .mp3 download after import would modify the download client "copy", resulting in breaking the torrent.
