I have a creo file with no features but its file size is 3052 kb. I would appreciate your response. Please find the file attached.
It must be an old file that has had stuff deleted from it, yes? I just created a new file (Creo 4.0, M090) with no template (empty) and its size is 34Kb. I think there's a lot of "baggage" and other remnants of stuff left in a file even after all the features have been deleted. I don't know what kind of persistent junk is retained in the part database, but I wish there were a way to purge it.
Is this a new file created in Creo 3 M160?
Is it an older file that has had the features deleted from?
Are there any relations or parameters in the file?
Are you using Windchill with your files?
There are many reasons a file size grows and does not shrink when objects are removed.
Please find it attached.
1.] there is some history saved in the file, for example it was saved in Windchill Commonspace
2.] I guess the file was improperly cleaned
3.] you have to send the file to PTC Support if you want to get the answer to your question
4.] I opened the file in Notepad++, as you can see in the following picture the file contains thousands of strange lines corresponding to excessive data.
