Caching

[SimoneManini]

You're doing a great job. I use and really appreciate Quantum Manager.

My only problem (and I think many others) is the lack of a caching system.
I manage a sports newspaper and have a 13-year-old photo archive with numerous folders and files. To create the folder tree, Quantum Manager makes a direct request to the server (quantumtreecatalogs.php > getDirectories function). The server takes a long time to respond, so every time I open Quantum Manager, I don't see the folder tree for several seconds (10-15 seconds).
For this reason, a caching system would be very useful.

One approach could be:

1. Save the scan result: At the end of the scan, instead of sending the result directly to the browser, save it to a file.

2. Check the cache at the beginning: When a new getDirectories request arrives, it checks whether the cache file exists and whether it's still "valid" (for example, whether it's not too old).

3. Return data from cache: If the cache file is valid, read it and send the data to the browser, bypassing the slow scan.

4. Charge for your work! Quantum Manager is too good to give away for free!

yes, I know about the problem with multiple folders and files. In the new version, I built the entire architecture differently. But when I will bring the new architecture to release is unknown.

What you suggested with the cache, in principle, is a sound idea, you can think about it and make it as a setting when there are an unrealistically large number of folders. There, you need to cache the folders themselves, you can reset the cache when the folder name changes or a new folder is created. The file cache should be stored in the directory itself, you need to create some hidden files for metainformation.
You need to think about it, but the idea is sound.

Regarding payment, I will express my personal opinion, the era of selling individual extensions has passed and the business should be built differently, not from selling a separate component.

Great dmitriitux!

Unfortunately, I haven't had time to try the suggested solution yet. I was planning on trying it out and, if it worked, sending it to you.

However, if you've changed the architecture, I think it's wiser to wait for the new release... when you can.
