FATAL CiscoConfParse could not open xxx.xxx.xxx.xxx.txt file

Question

I have some cisco config files in the folder. I wrote the for loop to iterate thru each config files and find vlan1 ports as follows. I check the permissions and security for the folder, files for all the config files and they're the same. Ironically, CiscoConfParse can open, read, and produced results for some config files, but not others. if I removed the config file that it cannot open, then it produced the result as expected. When I put that config file back into the same folder, then it could not open and gave the [FATAL] filenotfound error. I researched online and found some suggested solutions such as performing chkdsk /f /r and then sfc /scannow to scan and repair the corrupted files. I did all that but the issue still persists. I hope someone has solved this issue before and help. Thank you

This problem was also reported as Github issue #204. The problem could not be reproduced. Note: before ciscoconfparse version 1.6.0, there was no config encoding parameter. Explicit encoding was added in ciscoconfparse version 1.6.0
