Slow file menu after firmware update

I updated to the latest firmware today (hoping it might help with my inconsistent first layers).  Now, when I try to scroll through the folders on my USB sticks, it is painfully slow.  When I get to the bottom of what is showing on the screen, to go down one folder, it hangs for up to 3 seconds.  In order to get to the bottom of the files list (I have about 40-50 folders with files on them on the card), it is taking almost a minute just to scroll down.  Before the update, when I was using firmware from a few months ago, the menu wasn't super snappy and responsive, but it was nowhere near this slow.

I have a different brand USB stick on both of my machines, so I know it's not the stick.  Both of them are behaving identically since the update.

Any suggestions?  I will always be running the machines off of the USB, not online, and I will always have folders on the sticks, since I print a lot of the same things over and over again.  I don't want to have to sit at the printer for a full extra minute just trying to scroll through the files every time I go to print.

And now that I'm actually trying to print something, it's not showing the preview image when I try to print.  Also, the other menus are fully responsive, it's just trying to navigate the USB drive.

RE:

Have you re-sliced the files? New versions of the firmware need a different embedded image format in the gcode file. That could be causing both problems. 

Lots of discussion on here about the format change.

No, I haven't resliced, and don't intend to.  I have about 200 sliced files that I've already tweaked and have set for printing.  I honestly don't care about the preview image, if I have to go without it that's no problem, but if I have to reslice hundreds of files to get the menu to work correctly, that's a problem.  Is there any way to get around that?  Again, if I don't see the preview image I'm fine with that, but I just can't go back and reslice all of these files in a reasonable timeframe.

Ug, I hate this stuff so much.  My MK3S+ machines just work, they just print what I tell them, and the MK4 has been filled with so many headaches, I just want them to print reliably.  I don't need any bells and whistles, I just need to know that when I press print, I can walk away, and come back to a finished product.  I guess I'm going back to old firmware for now.

I just put in a flash drive with 40 empty folders, nothing on the drive except for the folders, and navigating through them is slower than when using the 5.0.1 firmware.  It's definitely more responsive than the drive that had folders filled with files, but I don't understand how a machine that has a new, upgraded, modern processor just lags so much scrolling through a file list.

RE: Slow file menu after firmware update

Note that some kind of "file manager" implemented in the printer FW is not the primary purpose of the printer FW. FW's primary job is to control the printer so that it does its job of creating prints. You can manage files on your computer and if you don't want to control the printer remotely, the solution is to upload only what you need immediately to USB. It is even much safer than saving such a lot of files only on USB, it is the best way to lose files.

In 5.0.1, the file manager was slow, but usable.  In 5.1.2, it's so slow as to be almost completely unusable.  Loading just the files needed for each job onto the USB just is not a realistic use case.  I've got probably 75+ folders on each of the SD cards on my MK3S+ machines, and after the initial 5-10 seconds for them to load, I can scroll through them without any hiccups or pauses.  In the MK4 using 5.0.1, scrolling was slower, it felt like it was lagging, but not so much that you couldn't scroll through the folders to find the one you want.  I don't understand why, with a much faster processor on the MK4 vs. the MK3, it would struggle just to scroll through a list of folders.

 

I have never, on any printer I've ever used, been unable to keep a collection of files/folders on the card, and just run it from there.  I'm not talking about hundreds folders and thousands of files, I'm talking about 50ish folders, with 2-7 files in each one.  The printer should be able to handle this, and I'm just confused as to why it is struggling so much.

RE: Slow file menu after firmware update

Same issue here... I just updated one of my mk3s+ to a mk3.5 (same board as mk4). 
Same problem with EXTREMLY laggy SD-card menue. To the point that it is unusable...

Support is aware of the problem, but no solution in sight for now.
I´m running a business with a couple of printers. Have the same files on my mk3s was absolutly no problem. But the mk3.5 is unable to read 70ish folders with 2-10 files each.

I'm really hoping this is fixed in the next firmware.  As of right now I have both of my MK4s back at a firmware that is several versions old, and while the file menu still feels way more sluggish than it should, at least it doesn't freeze up when trying to scroll through a list of folders on the card.
