**CorOS Version:** 3.0.0 **Describe your issue:** When I load up an IR block, the default IRs that were set before updating to V3.0.0 are missing. **Steps to reproduce your issue:** 1. Click/tap on the grid on any preset 2. Add an IR block 3. See that the IR block has a warning and that the default IRs are marked as missing. **I expected this to happen:** When I add an IR block, I expect the default values to include the IR files. **I have tried the following things:** I have tried going back to a preset using my default IR Block settings and setting this as the defaults - this fixes the issue going forward. Adding an IR block after this works as expected. ---

I have the same problem, I thought that it was because I deleted and ‘reloaded’ all my IRS in the new folder/subfolder structure… The strange thing is that even if the IR loaded block display a ‘warning’ icon, and mention the missing IR File , the file is indeed present , I simply had to reselect it it everything was ok… (but it would be tedious if you have a lot of preset using IRs…) ---

All my presets are fine. I think it’s just the default values. I’m guessing the memory structure/filesystem changed as part of the update and the links didn’t update. ---

Strangely, some of my IRs are recognized , while others aren’t … The new folder structure acts like a ‘virtual file system’ , but in reality all the uploaded IRs are (or ‘should be’) physically stored in the ‘IR Library’ (the very top node of the structure). The folder/subfolder structure is merely a virtual filesystem containing symbolic links to the ‘real’ IRs files (stored in the flat ‘IR Library’), it is only a way for us to quickly find what we want… But there might be something wrong in the upload process from Cortex Control because : - I uploaded my first set of IRs by dragging the file in the ‘IR Library’ , and from this IR LIbrary folder, I drag’n’droped those files into a subfolder. (and I think that’s why some of my presets are still recognizing the IR files) - Since it way tedious to select , drag-drop specific files from the IR Library onto other subfolders, I changed the way I uploaded them into my QC: - I first created my subfolder, then clicked on its name, and dropped my IR files directly into the ‘subfolder’. I double-checked that the IR Files were in reality still available from the top node ‘IR Library’, and it is indeed the case ! - But I suspect that those IR files are no longer directly recognized by the IR block in my Presets ! That’s dumb, because it should not matter if you drag an IR file into the ‘IR Library’ and then create the link to it into a subfolder, or drag an IR file directly into the subfolder (_it should add the IR file into the IR Library and create the same link as in the first method…_.) I will investigate if my theory is right or not… ---

> [@BenM](#): > > Strangely, some of my IRs are recognized , while others aren’t … This gives me some comfort. This issue as a whole could be a nightmare for some. Makes me wonder about preset management as well (folder system updates). Please follow up your findings.
