Rotating files for saving snapshots

I have some cctv camera at home. I want to save the snapshots of this in a folder. I know how to get the snapshots using the http request node and also saving it with the file node. But I want a solution in which I have to save only 10 snapshots all together and for the 11 th snapshot, the oldest one of the present should be erased and 11th should be written. To sum up, a simple system of file rotation after 10 snapshots.

If you add the date/time to the file name, you could use the watch node to watch the folder and have it kick off a flow that use one of the contrib file nodes to read the names of all the files. Sort the filenames and delete the oldest ones.

You can quite easily achieve this with the fs-ops nodes.

e.g...

↑ adjust the values in the inject to suit ↓ (the rest will just work)

I found that this was removing the newest file than youngest, maybe due to some mixing in configuration. But I was able to achieve the requirement with some slight modification.

  • your version does not check the created timestamp & might delete random files.
  • Also, if the deletion fails you will end up with an infinite loop.
  • Also, you are getting the full DIR but only deleteing 1 file at a time then looping back and getting the full directory again (BEFORE the deletion!) - it is likely you will hit an issue where the DIR listing contains a file that has been deleted & cause errors.

Here is a slightly modified version - please check again the files if says it will delete.

I checked the updated version. But still it is deleting the oldest files

something isnt right.

could you run it again and copy the output from the last green debug msg like this...

then psate the copied msg into a reply
```
like this (between three backticks)
```
