[WROIATE]

I got the same exception with long title. Is there any way to solve the problem?

[Robonau]

i believe the error is an OS error. the different OSs have different limits, 214 chars should be fine in all of them tho.
Windows : 256
Linux: 255 (EXT4: 4096)
Mac: 255

i would expect truncating to 254 chars would fix it (idk about the 214 chars breaking tho, maybe he counted wrong)

I just found that 214 characters is the parent folder's length (Book Name), the full path length is 301 (/tmp/Tachidesk/manga-cache/<Source Name>/<Book Name>/Chapter/001.tmp)
