Need a server to try this on? Antihost offers Linux VPS plans with NVMe storage, full root access and a 14-day free trial.
When FileZilla connects but an upload fails with “permission denied,” the SFTP server—not FileZilla—has rejected the operation. The usual causes are a target directory or parent directory without write/execute permission, a Windows NTFS ACL denial, or an OpenSSH chroot whose root is writable or owned incorrectly. You normally do not need to make the account root. Correct the remote path, ownership, group membership, ACLs and chroot layout instead.
What a successful connection does—and does not—prove
FileZilla can authenticate an account, list a directory and still be unable to create, replace or rename files. Authentication proves only that the server accepted the password or key. Authorization is checked separately for every operation.
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →- Read/list access: allows the account to see a directory or download a file.
- Write access: allows creation of a new file in the directory.
- Execute or traverse access: on Linux, allows the account to pass through a directory on the way to the target. A parent without execute permission blocks access even when the final directory is writable.
- Replace, rename and delete access: is generally controlled by the containing directory, not just by the existing file’s mode.
Therefore, changing a file’s mode after an upload will not fix a directory that rejects creation. Find the exact remote directory FileZilla is using, then have an administrator inspect every directory in that path.
First checks in FileZilla
Use SFTP and the intended server account
- Open File → Site Manager and select the site.
- Set Protocol to SFTP – SSH File Transfer Protocol. Do not use plain FTP or FTP over TLS when the server account is configured only for SFTP.
- Verify the host name, SSH port (commonly 22, but the administrator may use another port) and the exact user name. A similarly named account can have a different home directory, group membership or chroot.
- For key authentication, choose Logon Type → Key file and select the private key that matches the public key installed for that user. “Server refused our key” commonly means the public key is missing, the key belongs to another account, or the server is reading a different authorized-keys location.
Do not test by switching to a root login unless the server administrator has explicitly permitted it. A root test can hide the real path or ownership problem and creates unnecessary security exposure.

Record the remote directory shown after login
Look at FileZilla’s remote directory field and the directory listing immediately after authentication. The visible path may be the user’s home directory, a chroot-relative path, or a server-selected starting directory. Uploading to a different folder than expected is often a path problem rather than a transfer problem.
If the administrator wants the session to open in a specific directory, OpenSSH can use a forced internal-SFTP command such as:
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsForceCommand internal-sftp -d /uploadsThe -d option chooses the starting directory; it does not change the chroot boundary. The directory must exist in the account’s view of the filesystem, and the account still needs permission to write there.
Linux and OpenSSH: repair permissions without granting root
Check the complete path
An administrator should inspect the target and each parent directory. For a path such as /srv/sftp/alex/uploads, check /srv, /srv/sftp, /srv/sftp/alex and /srv/sftp/alex/uploads. The account needs traverse (x) permission on every parent and write plus execute permission on the directory where it creates files.
namei -l /srv/sftp/alex/uploads
ls -ld /srv /srv/sftp /srv/sftp/alex /srv/sftp/alex/uploadsnamei -l displays ownership and mode bits for each path component. The output helps distinguish a writable final directory from a parent that blocks traversal.

Use a dedicated directory and least-privilege ownership
Create an upload directory that is owned by the SFTP account or by a group dedicated to file exchange. Adapt the names and paths to the server’s policy; do not run these examples blindly on a production system.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
sudo mkdir -p /srv/sftp/alex/uploads
sudo groupadd sftp-upload # only if the group does not already exist
sudo usermod -aG sftp-upload alex
sudo chown root:sftp-upload /srv/sftp/alex/uploads
sudo chmod 2770 /srv/sftp/alex/uploadsThe set-group-ID bit in 2770 makes new files inherit the directory’s group on systems that support it. An alternative is to make the user the owner:
sudo chown alex:alex /srv/sftp/alex/uploads
sudo chmod 700 /srv/sftp/alex/uploadsChoose one ownership model that matches the people or services that must read the files. Avoid broad modes such as 777; they allow unintended users to create, replace or delete content.
Understand directory permissions
ron a directory permits listing names.xpermits entering or traversing it and accessing an item whose name is known.wpermits creating, deleting and renaming entries when combined withx.
For example, a user may be able to list a directory but not upload because it has r-x rather than rwx. Conversely, a directory may be writable but unreachable because a parent lacks x.
OpenSSH chroot: the directory layout that avoids upload failures
A chroot changes what the SFTP account sees as the filesystem root. OpenSSH requires the chroot directory and its path components to be controlled by the system; a restricted user must not be able to write to the chroot root itself. Put a writable child directory inside it.

Working layout
/srv/sftp/alex/ # chroot root: owned by root, not writable by alex
└── uploads/ # writable by alex or the approved groupIllustrative commands are:
sudo chown root:root /srv/sftp/alex
sudo chmod 755 /srv/sftp/alex
sudo mkdir -p /srv/sftp/alex/uploads
sudo chown alex:alex /srv/sftp/alex/uploads
sudo chmod 700 /srv/sftp/alex/uploadsIf the account is chrooted to /srv/sftp/alex, FileZilla will see that directory as /; the writable folder appears as /uploads. Trying to upload directly to the chroot root will fail by design. Set the session’s starting directory to /uploads if desired.
Typical sshd_config pattern
Match Group sftpusers
ChrootDirectory /srv/sftp/%u
ForceCommand internal-sftp -d /uploads
X11Forwarding no
AllowTcpForwarding noAfter any configuration change, validate before reloading the SSH service:
sudo sshd -tA successful validation produces no output. If it reports an error, correct that error before restarting or reloading SSH. Keep a current administrative session open while changing remote-access configuration so a mistake does not lock out administrators.
Windows OpenSSH: use NTFS ACLs and a compliant chroot
Windows OpenSSH uses NTFS access-control lists rather than Linux mode bits. A user can authenticate successfully while an ACL on the target folder or a parent denies creation. Microsoft recommends a local ChrootDirectory, retaining owner permissions for SYSTEM and Administrators, and providing each user a writable directory inside the chroot.
Recommended layout
C:SFTPalex (chroot root; controlled by SYSTEM/Administrators)
└── uploads (write permission granted to alex or an approved group)Do not grant the restricted user write permission on C:SFTPalex itself when it is the chroot root. Grant write and modify rights on uploads instead. The exact principal and inheritance choices depend on whether files are shared with a service account or other users.

Inspect and repair ACLs
icacls C:SFTPalex
icacls C:SFTPalexuploadsAn administrator can grant access to a named account or group with icacls, for example:
icacls C:SFTPalexuploads /grant alex:(OI)(CI)M(OI)(CI) applies inheritance to files and subdirectories, and M means modify. Replace the account and path with values appropriate to the server. Preserve the existing SYSTEM and Administrators control entries on the chroot root; removing them can make the chroot invalid or impair administration.
Validate the OpenSSH configuration with:
sshd -tThen review the OpenSSH service logs and Windows Event Viewer for the failed login or transfer time. Logs often identify the rejected path, ACL or chroot check more precisely than FileZilla’s summary message.

Upload authorization and the mode assigned to a newly created file are separate issues. The SFTP server applies the remote user’s umask to the creation mode. Red Hat documents a default creation mode of 0644 before umask restriction (Red Hat, 2026). The effective result can therefore be more restrictive, such as 0600 or 0640, depending on server and account settings.
On servers using the SFTP subsystem, administrators may control behavior with server-side -m and -u options. Change a umask only after deciding who should read, modify or execute uploaded files. A permissive umask can expose credentials or private uploads; an overly restrictive one can prevent a downstream service from processing them.

If the transfer succeeds but another application cannot read the file, inspect the resulting ownership, group and mode on the server rather than repeatedly changing FileZilla settings.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Read FileZilla’s detailed error and server logs together
Capture the complete transfer log, including the remote path and the operation that failed. “Permission denied” while creating a new file points to directory permissions or ACLs. A failure during overwrite, rename or delete may indicate that the containing directory is not writable, that the existing file is owned by another account, or that a server policy blocks the operation.
On FileZilla Pro Enterprise Server, behavior settings can re-enable detailed errors for failed permission changes. On Windows OpenSSH, inspect the service log and Event Viewer after running sshd -t. On Linux, use the SSH/SFTP service logs appropriate to the distribution and init system. Match timestamps and usernames; a log entry for a different account can lead to a false diagnosis.
Deployment choices and their practical consequences
| Choice | Permission model | Directory requirement | Best fit |
|---|---|---|---|
| Native Linux/OpenSSH | POSIX owner, group and mode bits; optional ACLs | Write and execute on the upload directory; execute on every parent | Teams comfortable managing Unix ownership and service configuration |
| Windows OpenSSH | NTFS ACLs, inheritance and Windows principals | Writable child directory inside a compliant local chroot; SYSTEM/Administrators retain control of the root | Windows-based operations and existing Active Directory or local-account administration |
| Chrooted account | Permissions are evaluated inside an isolated filesystem view | Chroot root is controlled and non-writable to the user; writable child is required | Restricting the account to an exchange area |
| Non-chrooted account | Normal filesystem permissions or ACLs | Target path must be reachable from the account’s ordinary namespace | Trusted automation that needs several approved paths, with careful ACL design |
| Self-managed SFTP | Administrator controls users, ACLs, chroot and logs | Requires ongoing patching, monitoring and recovery procedures | Organizations needing infrastructure control or custom integration |
| Managed SFTP hosting | Provider-specific users, folders and ACL controls | Provider must expose the upload directory and permission settings you require | Teams that cannot edit server ACLs, ownership or sshd_config |
A complete diagnostic sequence
- Confirm identity: verify the protocol, host, port and exact username in Site Manager.
- Confirm authentication: for key login, check that the matching public key is installed for that username.
- Confirm the namespace: record the remote path FileZilla displays and determine whether the account is chrooted.
- Try the intended writable child directory: for a chrooted account, use a path such as
/uploads, not the chroot root. - Inspect Linux path permissions or Windows ACLs: check the target and all parents, not only the file being replaced.
- Validate OpenSSH: run
sshd -tafter configuration changes and correct any reported error. - Review logs: correlate the FileZilla timestamp, username and operation with SSH/OpenSSH logs or Event Viewer.
- Check post-upload mode: if creation works but a consumer cannot read the file, inspect umask, group ownership and resulting mode.
- Retest with the least privilege: upload a harmless test file, list it, download it, and remove it only if the account’s policy is supposed to allow deletion.
Symptoms and targeted fixes
| Symptom | Likely cause | Action |
|---|---|---|
| Login succeeds; upload to the home directory fails | Home or chroot root is intentionally non-writable | Use or create a writable child such as /uploads; keep the chroot root controlled. |
| FileZilla opens in an unexpected folder | Server-selected starting directory or chroot-relative path | Inspect the remote path and set ForceCommand internal-sftp -d /uploads if the administrator wants a different start location. |
| New file works; overwrite or rename fails | Containing directory lacks write permission, or an existing file has a different ownership/policy | Check directory write/execute permission, ACLs and the server’s rename policy. |
| Windows account authenticates but cannot create files | NTFS ACL denies modify/write, often through a parent or inherited rule | Use icacls, preserve SYSTEM/Administrators control of the chroot root, and grant the account access to the writable child. |
| “Server refused our key” | Wrong private key, missing public key or wrong username | Verify Site Manager’s key file and the server-side authorized key for the same account. |
| Upload succeeds but another service cannot read it | Umask or group ownership produced a restrictive mode | Inspect the resulting mode and ownership; adjust group policy or SFTP umask deliberately. |
| Configuration change prevents login | Invalid sshd_config or non-compliant chroot ownership |
Run sshd -t, read service logs, restore the last known-good configuration and keep an administrative session available. |
When you cannot change the server
If you are not the server administrator, FileZilla cannot bypass a denied ACL, ownership rule or chroot restriction. Send the administrator the exact username, remote path, timestamp, operation (create, overwrite, rename or delete), and complete FileZilla error. Ask for a writable directory inside the account’s allowed area rather than root access.
If your organization cannot administer Linux permissions, Windows ACLs, chroot layout or sshd_config, a managed SFTP service can be a fallback—but confirm that it provides per-user upload directories, ACL controls, audit logs and a way to set the starting directory before migrating data.
