Quickbooks Desktop Pro very slow - scanning the Txn folder on window opens

I appreciate your detailed description of your concern, @BrianHFASPS . You’ve done a great job isolating the problem so far. Since QuickBooks Desktop is scanning a very large number of files locally and over the network, performance can be impacted by data integrity issues or connectivity glitches, even on a fast wired network.

To help us further troubleshoot and fix any underlying data or program problems, I recommend installing and running the QuickBooks Tool Hub. This is an official Intuit utility that combines several key diagnostic and repair tools, including those for network issues, company file errors, and program problems.

1. Close your QuickBooks.
2. Download the recent version (1.6.0.8) of the QuickBooks Tool Hub. Save it somewhere you can locate it.
3. If you've installed Tool Hub before, you can find out which version you have. Select the Home tab. The version will be on the bottom.
4. Kindly open the file you've downloaded. It is named QuickBooksToolHub.exe.
5. Follow the on-screen steps to install and agree to the terms and conditions.
6. Once done installing, double-click the icon on your Windows desktop to open the tool hub.

Step 2: Run Quick Fix My Program

1. In the QuickBooks Tools Hub, select Program Problems.
2. Select Quick Fix My Program.
3. Start QuickBooks Desktop and open your data file.

Following these steps can help improve QuickBooks’ responsiveness when accessing your file over the network. Please try them at your convenience, and feel free to reach out if you need further assistance or if the issue persists.

we are having the same exact issue, both with 23 and 24.

as expected, ArielI's solution doesn't solve anything.

Need help with this asap please....

I called [removed] and the support rep it's a known issue and it's being investigated ?

she also mentioned 17 other calls with similar issues today.

Can you confirm it's a known issue ???

Yes, there is an open investigation inv-129564.

Call support and make sure to get your email on the list for a fix.

The issue is the workstations are opening up dozens and dozens of files from that txn folder.

There is a known issue after a update went out last Friday.

There is an open investigation inv-129564

Call support and see about getting your email on the list for the fix.

Rename the attach folder located in the same location of the data file. This will break your documents until they fix it.

Yeah, renaming the folder IS NOT A FIX!!!!

The fix is to run QB update, use the reset option.... restart pc, run QB for updates to complete.

Make sure ALL updates are installed.... reboot twice if necessary.

THEN from control panel, run repair on QB....restart and the PC should stop opening lots of files from the ATTACH folder. 
The QB HUB Tool is a JOKE! Absolutely a waste of time to use!

I will try this in a few minutes. We've been having this issue since yesterday, 7/30. I tried running fixes from Quickhub on both a local PC and our server (File Doctor wouldn't even open), I've tried condensing our company's file, renaming the Txn folder (it just finds it again), removing items from the Txn folder, nothing seemed to work. The odd thing is that a few others were able to get in while the other 4 users would get freezing, and not responding messages. We noticed that if you let the program sit for 20 minutes, it eventually will open fully, but certain operations were still slow.

The fix I have works everytime..

Run QB update, make sure to do the reset option...all the updates will not run, so you have to restart PC and run QB, you'll briefly see QB is installing...check to make sure ALL updates are applied... restart again for good measure..

After the restart, use control panel to repair QB.. restart and you should be good... no need to rename folders..

The Hub Tool is A JOKE!!! It has NEVER fixed anything for me.

Let me know if I can help?

I found out that I only had to do the repair via the Control Panel to fix the issue, or reinstall Quickbooks 24 altogether. Most of our installs were already up to the latest version (v34.0.4015 I believe). The first computer I did wouldn't let me do the repair. It kept getting error 1334 halfway through, and asked for an installation CD (never existed). I had to reinstall Quickbooks, and it worked fine after that. The second computer kept throwing errors during the repair for missing files, but let me ignore them. Worked afterwards. The next few PCs were a breeze. The one PC that had 4014 we left alone, because it didn't seem to have this issue yet. 

First off thanks for sharing this - spent the last 3 days trying to figure out what had happened... 

I performed these steps on about 5 machines and the server last night, and the issue was resolved. When I came in this morning and my client checked them, the issue had come back on two of the workstations pc's....

Any idea what would cause that? 

That's a good question that I'm trying to figure out. I had one PC start showing the issue again. Oddly, it was the one that kept throwing the file not found errors during the error that allowed me to ignore them and continue. I ended up reinstalling Quicksbooks 24 on that machine as well. The others I've done yesterday have not had an issue so far, so fingers crossed. I will say that doing a repair/reinstall to fix the issue is luckily a quick fix (that I wish I knew two days ago), since the computers are on SSD and are pretty fast. Though, I do hope they release an update to fix this soon. 

I have the exact same problem. One of our clients started having extremely slow load times and I also saw the affected machine going through every file in the attach folder. It also goes through every file again every time he performs an action which results in unusable performance. Quickbooks Tool Hub, Quickbooks Clean Reinstall, Quickbooks Repair, QuickbooksInstallDiagnosticsTool, and new User Profile did not resolve it for me.

I'm glad to see it's a known issue because it was driving us crazy.

One of our clients was having the same problem. Only one user was affected. Did procmon and found the same result. It was checking every file in the Attach folder on startup, and every time they performed an action resulting in it becoming unusable.

Attempted the Quickbooks Tool Hub, Quickbooks Install Diagnostics Tool, Quickbooks Repair, Clean Reinstall (removing all quickbooks data from registry, programdata, localappdata, roaming), and all sorts of other finagling. Nothing worked for us so far.

This fix works for me every time.

Run All the QB updates from the help menu, but make sure to check the reset option, this will force the updates. Restart QB and the PC until you see all the updates installed.

After than, from control panel, run the QB repair and restart. 

Then the pc should work and not try to open lots of files from the attach folder

I appreciate your efforts in applying the troubleshooting steps to help resolve the problem, danm1901.

Can confirm this worked on all 5 of my workstations.

Thank you!!!

Same issues here.  We manage several clients with Enterprise Edition and this update and the attach folder is the root cause of extreme slowness.  

INTUIT PLEASE RELEASE A NEW FIX FOR THIS ASAP!!!!!!!!!!  

I had one PC show the issue again, but a quick control panel repair of QB and restart fixed it...

The user is back up and running.

We are having the same issue. It is S L O W. When we called, we were told that it was being investigated and just to keep checking our QB Desktop to see when it starts working correctly again. That's not a fix. It's day 3 of only being able to do a few things as it takes a long time to do each function. We all need a real fix.

The fix I've described in several posts "Repair QB" is not a fix, but a work around.

All my users have been working all week without an issue.

Call support and get on the list for the fix when released.

You need to get on the contact list for Investigation INV-129564
