When you try to copy an Eagle library from an external hard drive to your local computer, you may encounter situations where the copy operation cannot be completed. This is usually caused by file occupation or system environment restrictions. This article will guide you on how to solve this problem by compressing files.

Possible Causes

The library's .library file may be occupied by an application
The device's environment settings may have accidentally restricted or blocked file operations

Solution

Compressing the library before transferring can effectively solve this problem. The specific steps are as follows:

Compress the library into a ZIP file
- Find the library folder you want to copy in the file manager
- Right-click on the folder and select "Add to archive"
- In the pop-up window, select the compression format as "zip"
- Choose "Store" as the compression method (this only packages without compressing, which can speed up processing)
Transfer and extract
- Copy the generated ZIP file to the target location (such as local D drive)
- Extract the file at the target location
Reload the library
- Open Eagle software
- Use the "Switch library" function to select the location of the library you just extracted
- Confirm that all data content is complete and correct

Other Solutions

If the above method still cannot solve the problem, you can try the following operations:

Right-click copy and paste the library on the external hard drive to the desktop
Use Eagle software to read the library on the desktop
Check if the same problem still exists on the local hard drive

Why can't I copy the library from my external hard drive to my local computer for backup?
