Cannot change read only attribute file

Jump to bottom. Labels area-System. Milestone Future. Copy link. As I can see from provided logs, the error occurs when trying to change the ReadOnly file attribute from true to false during this line execution: item. ReadOnly ;. ArgumentException: Invalid File or Directory attributes value. Parameter 'Attributes' at System.

IO untriaged labels Sep 21, I noticed your method RemoveReadOnly is called in three places. Reasons why I doubt it now: An empty file with this name does exist and I can see it; When the file is missing, item.

ReadOnly; another exception is thrown when the file is missing, as danmoseley have already mentioned above: Unhandled exception. Jozkee mentioned this issue Nov 17, FileInfo reports wrong attributes on OSX Jozkee closed this Nov 17, Sign up for free to subscribe to this conversation on GitHub.

Ive been experiencing this issue since the Creators Update, not precisely sure on exactly when that was. It immediately reselected without user approval or interaction. Note: this is affecting all drives, external and internal, with exception of drives using filesystems that do not support ownership of files or folders.

Click the Owner tab. Click the Edit button. Highlight your username. Check the box for Replace owner on subcontainers and objects. Click OK to close each dialog until it begins applying permissions. If you get any errors, click Continue.

When done, close the Properties dialog. It must be closed and re-opened. Right click the drive, click Properties. Click the Permissions tab. Click the Change Permissions button. Add your account if needed. If Administrators, System , and your account do not show Full Control for This folder, subfolder, and files , highlight each and click Edit.

Change the permissions to Full Control , and the Apply to: box to This folder, subfolder, and files. Use this list to set the permissions.

For Special check 6 only. Everyone should have one entry shown as Special. Creator Owner should have one entry shown as Special. It will have Full Control permissions and Apply to: is Subfolders and files only. OK back to the Permissions tab if needed and check the box for Replace all child permissions with inheritable permissions from this object.

You'll get a warning that explicitly defined permissions will be removed. Click Yes to continue. If you get any errors, just click Continue.

It works! You're a beaut! Thanks for getting this sorted And thanks for the help Byteman! I think it was taking ownership manually that did it, rather than using the downloaded tool you linked.
