CreoJS API Reading files from network drives

ilyachaban — Mon, 26 Jan 2026 13:28:50 GMT

Hello, is there any possibility to read files from network drives?

try { print(readFileAsString("\\\\10.170.84.24\\Standard\\ProE_standard\\Relace\\Relace PRT.txt")); } catch (e) { print("FAILED: " + e); }

I need to read fresh relations so all models actual relations. The only one place in our company provides relations is network drive.

Do you have web_link_file_read config option set to yes?

Yes, I do and it works if I read from 😧 or C: drives. But when i reach out to network drive it can't read a thing

It probably has to be a mapped drive.

Did you also tried without the.blank character, here

„Replace PRT.txt“ with „Replace_PRT.txt“

try {

print(readFileAsString("\\\\10.170.84.24\\Standard\\ProE_standard\\Relace\\Relace_PRT.txt"));

} catch (e) {

print("FAILED: " + e);

}

Or replace the IP by the hostname, or copy the file to a local one or change the directory first.

Is readFileAsString Unicode?

I've tried 3 ways to call the drive. One of them was mapped drive, second one was ip adress, and third one UNC path. Nothing worked. But if i use local 😧 or C: drive it reads file fine.

Renaming file doesn't do anything due to reading same file but from C: or 😧 drive works without problem

You followed this settings:

Not sure, but web based apps have no access to file folders, make sure to add the config path.

Make sure of setting config options and creo_js_app.conf correctly:
- config options:
  - web_link_file_read yes
  - web_link_file_write yes
- creo_js_app.conf:
  - readable_folders = ${CWD}; C:\xxx\xxx;
  - writable_folders = ${CWD}; C:\xxx\xxx;

Information of creo_js_app.conf:

The configuration file for the Creo.JS setting
ONLY limited options are introduced in the Creo.JS user guide.
It is loaded automatically from the current working directory when launching Creo Parametric

creo_js_app.conf:
- readable_folders = ${CWD}; C:\xxx\xxx;
- writable_folders = ${CWD}; C:\xxx\xxx;

IT WORKED. Thank you so much.

P.S.

I want the PTC community to understand just how close I am to swearing in this thread.

I’ve spent two weeks on what should be a basic task: reading a file from disk. The blocker is a config file that has no documentation—not even the basics. There’s no reference for its syntax, no list of options, no explanation of what it controls or how it’s supposed to be used. Just… nothing.
