Conversion Error [3, 'The system cannot find the path specified.']

[Redvis]

Hi,

I encounter strange error lately. It is a problem with my OS or calibre itself? Error occurs when I try to convert book or change metadata.

calibre, version 1.5.0
ERROR: Unhandled exception: <b>error</b>:(3, 'CreateFile', 'The system cannot find the path specified.')

Most likely that error is caused because you have some files in your calibre library folders that have names that are too long for windows. I suggest moving your library to something like c:\library to shorten the paths.

Thanks a lot! I removed all latin extended-A signs from my path and now it work.

But I am sure that it didn't couse any error in earlier versions.

Had Calibre from the start of this year and when I recently updated it for the first time I get the message described above. I tried what you proposed Kovid but didnt work. I cannot make conversions. I uninstalled and reinstalled it, nothing again. I even put a previous version but the problem persists. Very frustrating! Any ideas? (operating system: Windows 7, 32 bit)
Thanx for any help

Something is blocking (or clearing ) the temp folder Calibre workers use during conversion (and other intermediate steps).
There is a FAQ at the official site on how to move the location of TEMP if you can't just have you A/V allow Calibre* to use it
