Lock a client folder automatically when you finish work
By Param Nimbark. Last updated 2026-10-24.
You keep each client's files in a folder on your own Windows PC. When the working day ends you want that folder locked without having to remember, and back the next morning with a password only you know. This guide starts with what Windows already gives you for free, with Microsoft's own pages linked. Then the Seqtrix way, built on its free Clock out template, including the one rule in Seqtrix 0.16.0 to know before you set it up, and a plain list of what Seqtrix cannot do.

The job, in plain words
- • The files: each client has a folder on your Windows PC, with their books, payroll, statements and the papers they sent you.
- • The worry: the folders sit there readable all night, and someone else may use this PC after you: a new junior, an articled assistant, someone at home.
- • The routine: when you stop, save what is open, lock the client folder and lock the PC, every working day, without having to remember.
- • The morning: open the folder again in one step, with a password only you know.
The free way first: what Windows already does
Start with what you already have. Each fact below is from Microsoft's own pages, linked under each card. Checked on 24 October 2026.
Lock the PC: Windows key+L
Microsoft's list of keyboard shortcuts gives Windows key+L as "Lock the computer." It is one keypress, and it is worth pressing every time you stand up. It locks the screen, not the files: your Windows password or PIN opens everything again, and it encrypts nothing on the disk.

Encrypt the folder with EFS (not on Windows Home)
Right-click the folder, select Properties, then Advanced, and select Encrypt contents to secure data. Microsoft says file encryption is not available in the Home edition of Windows. This is the Encrypting File System (EFS), which protects individual files on NTFS drives with a public-key system, and the cipher command does the same from a command line: cipher /e encrypts and cipher /d decrypts. EFS has no password of its own: the key is protected by your Windows account's EFS certificate, and Microsoft's EFS documentation says encryption and decryption are completely transparent to the user. So the folder opens normally for anyone signed in as you; what it guards against is someone reading the disk without your sign-in, such as a lost or stolen laptop.
Sources: How to encrypt a file or folder, File encryption, Encrypting and decrypting data (Microsoft's archived EFS documentation), the cipher command. Checked on 24 October 2026.
Encrypt the whole drive: BitLocker or device encryption
BitLocker encrypts entire drives, and Microsoft describes it as addressing the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned devices. It is only available on Windows Pro, Enterprise and Education; it isn't available on Windows Home. Device encryption is the automatic version: on devices that qualify, including PCs running Windows Home, it turns on BitLocker for the Windows drive and fixed drives by itself. To see whether yours qualifies, open System Information as an administrator and look for Device Encryption Support. Microsoft also notes that a device using only local accounts remains unprotected even though the data is encrypted. Both work on whole drives, and Microsoft frames them around a device that is lost, stolen or decommissioned, not around one folder on a PC you are signed in to.

Run something at a set time: Task Scheduler
Task Scheduler is part of Windows. It can start a task at a specific time on a daily or weekly schedule, when the computer enters an idle state, or when a user logs on. It starts the program or command you give it, so the commands, and testing them, are yours to write.

What Windows Home lacks
On Windows Home there is no EFS and no BitLocker. If the PC qualifies, device encryption still protects the whole drive, but none of the options above encrypts a single folder on Home.
If you are on Pro and your worry is a lost or stolen laptop, BitLocker plus Windows key+L every time you stand up is free, and it may be all you need. What Windows does not give you is the routine: one client folder turned into a locked file at the same time every evening, the PC locked after it, and nothing to remember. That is the part Seqtrix does.
The Seqtrix way: the Clock out template
Seqtrix is a Windows app where you put steps in a sequence and fire it from a schedule, a hotkey or a click. Its Security Lock step encrypts a folder with AES-256-GCM using a password you set on the step: the folder becomes one locked file, named after the folder with .sflocked on the end, and the original folder is deleted. Clock out wraps that step in the rest of an end-of-day routine.

In the template's own words: Ends the working day properly: saves what is in front of you, logs the time, locks your work folder behind encryption, clears the clipboard so nothing sensitive survives the night, and locks the machine. These are its steps, as they ship:
- 1Save whatever is in front of youPress Key
Presses Ctrl+S in whichever window is in front. It saves that one window, not every open file.
- 2Let the save completeWait
Waits 1.5 seconds so the save can finish.
- 3Log the clock-out timeRun Command
Adds a line with the date, the time and "clocked out" to worklog.txt in your Documents folder.
- 4Encrypt the work folder overnight (pick your folder)Security Lock
The lock: Encrypt, on a folder. It ships with no folder and no password, and in Seqtrix 0.16.0 it cannot be saved in this sequence, so the setup below moves it into a sequence of its own.
- 5Clear the clipboardRun Command
Empties the clipboard, so the last thing you copied is not left on it overnight.
- 6Mute the machineMedia Control
Sends the mute key, which switches mute on or off: on a PC that is already muted, it turns the sound back on.
- 7Lock the workstationSystem Action
Locks Windows, as Windows key+L does. Your Windows password or PIN opens it again.
The one rule in Seqtrix 0.16.0: the lock needs a sequence of its own
The editor will not save a sequence that mixes a Security Lock step with other steps. It says: "A sequence cannot mix Workflow and Security actions. Use separate sequences." Clock out mixes them, so you cannot save it with your folder and password, and Test run saves first, so it stops there too. Run as it ships, it gets as far as the lock step, stops with "No password set for this step", and skips the clipboard, mute and lock steps after it. So set it up as two sequences:
- 1Make the lock sequence
Create a new sequence, choose the Security tab and add a Security Lock step. Choose Encrypt, then Folders, and Browse to the client folder. Type an Encryption Password and keep a copy in your password manager. Leave Unlock Mode on Manual. Save Sequence, with a name such as Lock Client A.
- 2Trim Clock out
Open Templates, search for Clock out and click its card. You land in the editor with its steps. Delete its Security Lock step, the one labelled "Encrypt the work folder overnight (pick your folder)", and Save Sequence. What is left saves the window in front, logs the time, clears the clipboard, mutes and locks the PC.
- 3Try it on a test folder first
Point the lock sequence at a test folder that holds copies of a few files, click Test run, then open the folder again as shown further down. Only then point it at the real client folder.
Make it run when you finish work
Neither sequence has a trigger yet. In Seqtrix, open Schedules, choose + New Schedule, pick the sequence and then a trigger. For the end of the working day:
On the Time tab, choose Weekly and tick Mon to Fri under On weekdays, at the time you stop work. The other choices are Once, Hourly, Daily, Monthly and Custom, which takes a cron expression. Give the lock sequence the earlier time and Clock out one a few minutes later, so the folder is locked before the PC is.
One key chord, pressed anywhere in Windows, when you stand up. Give each sequence its own chord, or keep the lock on a schedule and put Clock out on a hotkey.
Choose App closes and pick the program you work in, such as your accounting software. It fires when the last copy of that program exits, so it also fires if you close it at lunch.
Fires after you have been away for a set number of minutes, 15 unless you change it, so it also fires during the day whenever you step away that long. On Starter a System trigger is saved paused, with "The System Event trigger is in Advanced"; the 15-day Advanced trial on every install includes it.
On the free Starter plan every trigger counts toward its 3 schedules, hotkeys and app triggers included, and up to 2 sequences can hold a security step. Seqtrix has no trigger for Windows locking, signing out, shutting down or going to sleep. The full list is on schedules and triggers.
Before you rely on it
- • Seqtrix has to be running. Closing its window leaves it in the system tray (Minimize to system tray on close is on by default); Quit from the tray icon stops it, and its schedules with it. To have it start with Windows, turn on Launch on startup in Settings, which stays off until you do, then check after your next restart that the Seqtrix icon is in the tray.
- • Close the client's files before the lock runs. Seqtrix does not close them, and a file still open in another program can make the lock step fail part way.
- • Choose Skip for missed runs. If Seqtrix was not running at the set time, the schedule's missed-run setting decides: Skip, Run once or Run all. Run once is the default, and it means the lock, and Clock out with its PC lock, run as soon as Seqtrix starts the next morning. If the PC was asleep with Seqtrix running, the run fires as soon as the PC wakes, whichever you chose.
Getting the folder back in the morning
Seqtrix has no step that unlocks a folder, so the morning is one step by hand, with the password you set on the lock:
- • Double-click the locked file. It is named after the folder with .sflocked on the end. Seqtrix opens Decrypt Encrypted Folder; type the password and choose Decrypt & Open.
- • Or use the Security Dashboard. Open it in Seqtrix, find the lock sequence, choose Decrypt All and type the password.
The folder comes back where it was, with its files. Until the next lock, anything running as you can read them. Three things to know:
- • Unlock before you add anything. If a folder with the same name exists when the lock runs, for example because a new file was saved into a fresh folder of that name, the new locked file replaces the old one, and what the old one held is lost.
- • A folder still locked from yesterday stays locked. If you did not open it today, tonight's lock fails on that step because the folder is not there, and the locked file stays as it was.
- • Leave Unlock Mode on Manual. The Security Lock step also offers Scheduled (Auto-unlock at set time), but it takes one Unlock At date and time. Once that has passed the step refuses to run and changes nothing, so a daily lock with a scheduled unlock would stop locking after the first day.
How the keys work, the password caveats in full and what a recovery key can and cannot open: how the Seqtrix vault works.
What Seqtrix cannot do
The editor refuses to save a Security Lock step alongside other steps, which is why this guide uses two sequences.
There is no step that unlocks a folder, and a scheduled unlock is a single date and time. Opening the folder is a step you take, with the password.
Seqtrix does not close your files. If a file in the folder is open in another program, the lock step can fail, in some cases after the locked file is written and part of the folder removed. Close the client's files first.
Schedules fire only while the app runs, in its window or in the tray. A run missed while the app was closed follows the missed-run setting; one missed while the PC slept fires when it wakes.
The step saves its password in plain text in Seqtrix's data folder, as the vault page says in full, so anyone who can read your Windows account's files can find it. On a drive without BitLocker or device encryption, whoever has the disk has that file too. Your Windows sign-in, Windows key+L and drive encryption still matter.
Nobody can reset a step's password, us included. Keep it in your password manager.
Locking deletes the folder the normal way, without overwriting it first, so a recovery tool may find the old files until Windows reuses that space. The vault page covers clearing free space afterwards.
None of these is a trigger in Seqtrix. Use a time, a hotkey, an app closing or, on Advanced and Pro, idle.
The app checks your plan on launch and every 30 minutes, sending a hashed ID for this device. If it cannot reach the server it can fall back to the free Starter plan. Everything in this guide except the Idle trigger is on Starter, within its limits.
Common questions
Can Windows lock a folder automatically when I finish work?
Not one folder with a password of its own. Windows key+L locks the whole PC, EFS (not in Windows Home) encrypts files for your Windows account, BitLocker (Pro, Enterprise and Education) and device encryption cover whole drives, and Task Scheduler can run a command you write at a set time. Checked on 24 October 2026, on Microsoft's own pages, which are linked in the free way section above.
Which plan do I need for this?
Clock out is a Starter (free) template. Encrypt and the Time, Hotkey and App triggers are on the free Starter plan, which has 5 sequences, 3 schedules and up to 2 sequences with a security step. The Idle trigger needs Advanced or Pro, and every install starts with a 15-day Advanced trial with no card.
What happens if my PC is off or asleep at the set time?
If Seqtrix was not running, the schedule decides by its missed-run setting: Skip, Run once (the default) or Run all. Choose Skip for the lock and for Clock out, or they run as soon as Seqtrix starts the next morning. If the PC was asleep with Seqtrix running, the run fires as soon as the PC wakes.
How do I open the folder again in the morning?
Double-click the locked file, named after the folder with .sflocked on the end, type the password and choose Decrypt & Open. Or open the Security Dashboard in Seqtrix and choose Decrypt All. No step unlocks a folder every morning: a scheduled unlock takes one date and time.
Can I lock more than one client folder?
Yes. Give each folder its own lock sequence: when a step fails, for example because that folder is still locked from yesterday, the steps after it in the same sequence are skipped. Starter allows 2 sequences with a security step, Advanced 30 and Pro no limit.
Does Seqtrix need the internet?
The lock runs on your PC, but the app checks your plan on launch and every 30 minutes, sending a hashed ID for this device. If it cannot reach the server it can fall back to the free Starter plan. Everything in this guide except the Idle trigger is on Starter, within its limits.
What if I forget the password?
Nobody can reset it, us included, and no email or support ticket can open the folder. If you use Master Mode, its 24-word recovery key can help in some cases, which the vault page explains. Keep the password in your password manager.
