# Replace copies with hardlinks
|
|
|
|
You recently switched to a proper setup that supports Hardlinks and Instant Moves (Atomic-Moves).
|
|
|
|
And you would like to replace copies with hardlinks ?
|
|
|
|
If your Operating System supports it you could make use of [Jdupes](https://github.com/jbruchon/jdupes).
|
|
|
|
## Usage

!!! info ""
|
|
I won't cover every command :bangbang:
|
|
|
|
If you want to know what else [Jdupes](https://github.com/jbruchon/jdupes) can do please read the manual.
|
|
|
|
!!! tip
|
|
This process can take a long time and a pretty big hit on your resources depending on how big your library is, I did notice the first time it takes longer then the second time. Not sure if this is a cache thing or something else.
|
|
|
|
- That's why I suggest to do it based on categories (Movies, TV, Music etc).
|
|
- I don't suggest to use this on a cloud based setup.
|
|
|
|
```bash
|
|
jdupes [options] DIR1 DIR2
|
|
```
|
|
|
|
This will do a dry run and summarize at the end.
|
|
|
|
```bash
|
|
jdupes -M -r "/data/torrents/movies/" "/data/media/movies"
|
|
```
|
|
|
|
This will hard link all duplicate files without prompting.
|
|
|
|
```bash
|
|
jdupes -L -r "/data/torrents/movies/" "/data/media/movies"
|
|
```
|
|
|
|
!!! bug ""
|
|
Windows allows a maximum of 1023 hard links per file
|
|
|
|
!!! Warning
|
|
The `-Q` or `--quick` option only reads each file once, hashes it, and performs comparisons based solely on the hashes. There is a small but significant risk of a hash collision which is the purpose of the failsafe byte-for-byte comparison that this option explicitly bypasses. Do not use it on ANY data set for which any amount of data loss is unacceptable. You have been warned!
